Then 3.5 mmol of 3-(1H-imidazol-1-yl)alkyl-1-amine was added and the mixture was allowed to warm to 0 C. and was stirred for 12 h. The solvent was removed under reduced pressure and the remaining oil was redissolved in chloroform. Then the organic layer was washed two times by means of a saturated aqueous solution of NaHCO3, then dried over Na2SO4 and the solvent was removed. Purification was performed by means of centrifugal forced chromatography using a chromatotron device (Harrison Research Ltd.) utilizing silica plates of a layer thickness of 2 mm, and a CHCl3/MeOH gradient as eluting system resulting in 0.671 g (59.3%) of N-(3-(1H-imidazol-1-yl)propyl)-1-(3,4-dimethoxyphenyl)cyclopropane-carboxamide.

In toluene; for 5h;Heating / reflux; [0635] A mixture of <strong>[5955-72-6]2-chloro-5-nitro-benzimidazole</strong> (985 mg, 5.0 mmole) and 1-(3-aminopropyl)-imidazole (1.8 mL, 3 eq) in toluene (15 mL) was heated at reflux for 5 hr. The reaction was partitioned between EtOAc and brine to give a precipitate that was collected by filtration. Flash chromatography of this material (silica gel; stepwise gradient elution with mixtures of DCM containing 1, 2, 3, . . . 10% MeOH) afforded 2-[3-[imidazo-1-yl]-propylamino]-5-nitro-benzimidazole (550 mg) as a solid. This material was combined with 10% Pd on charcoal (500 mg), suspended in EtOH, and stirred under a hydrogen atmosphere (balloon) overnight. Removal of the catalyst by filtration and the solvent under reduced pressure left the crude 5-amino-2-[3-imidazo-1-ylpropylamino]-benzimidazole as a solid. A portion of this material (77 mg, 0.30 mmole) was added to a mixture of 319A (99 mg, 1.0 eq), an aqueous solution of HCl (0.60 mL, 1.0 M, 2 eq) and n-BuOH (1.5 mL). This was heated in a sealed vial at 120 C. for 20 hr. After cooling to RT, 572 (HPLC retention time (YMC ODS S7 3×50 mm): 1.20 min) was isolated by preparative HPLC.

Each diamine was measured in the amount of 0.05 g (approximately 0.3 mmol) and pooled together with the others in the group. Obtained diamine mixtures were dissolved in 5 ml of 1,2-dichloroethane and used for the syntheses. Each well of the 96-well filterplates was loaded with 0.2 ml of 1: 10 mixture of acetic acid: DCE, 0.03 ml of the diamine mixture in DCE (group 1, group 2, group 3, or group 4) to assure 0.04 mmol of the diamines per well, and shaken for 5 min at room temperature. Appropriate carbonyl compounds from the master plate (0.1 ml of 1.2 M solution) were added into corresponding wells of the reaction plates followed by the addition of (polystyrylmethyl) trimethylammonium cyanoborohydride, (0.020 g, 0.08 mmol per well). The reaction plates were sealed and placed on a shaker. The reaction was allowed to proceed 24-36 hours at room temperature. At the end, the reaction mixtures were filtered using a filtration manifold, and products were collected into four (one per group) collection plates. Solvents were evaporated in SpeedVac and formed residues were analyzed by mass spectrometry prior to biological screening. Mono and double alkylated products were observed in 1: 0.5 to 1: 2 ratios by mass spectral analysis.

95% In methanol for 3h; Reflux; 2-([3-(1H-imidazol-1-yl)propyl]aminopropyliminomethyl)phenol (2) This compound was prepared using a method similar to those previously reported [8,9]. To a solution of Apim (5.43 g, 43.4 mmol) in dry methanol (30 mL) was added salicylaldehyde (5.30 g, 43.4 mmol) with constant stirring. The resulting yellow solution was refluxed for 3 h and then stirred overnight at room temperature. The solvent was then removed under reduced pressure to give a yellow oil, which, on standing for 4 h, yielded yellow crystals of 2. The crystals were recrystallised from toluene, filtered, washed with cold, dry methanol and air-dried (9.5 g, yield 95%). M.p. 83-84°C (lit. 78-80°C). C13H15N3O (229.28): Calc.

A significant exotherm was noted when the mixture was swirled at room temperature. A stir bar was added to the flask and a temperature controller, 25 ml Dean-Stark trap, condenser, and bubbler were attached. The mix was stirred and refluxed at 120° C. under an argon blanket.

The mixture was heated to reflux for 2 h and then concentrated under reduced pressure affording crude esters 3 as thick oils or semi-solids. The phosphinate esters 3c,d were recrystallized from a mixture of toluene/hexane. The phosphonate esters 3a,b were characterized as oxalate salts. The oxalates were obtained in the following way; the crude ester (1.0 equiv) was dissolved in acetone (10 mL) and oxalic acid (COOH)2·2H2O (2.0 equiv) in acetone (10 mL) was added and the mixture was refrigerated.

The mixture was maintained at -78 °C for 5 min. The reaction was monitored by thin-layer chromatography (TLC). The excess of ozone was eliminated by bubbling nitrogen into the solution. Amine (RNH2) (0.1 mL), NaBH(OAc)3 (368.8 mg, 1.7 mmol), and CH3OH (8 mL) were successively added, and the mixture was allowed to reach 0 °C. After completion of the reaction (TLC monitoring, CH2Cl2/CH3OH, 30:1, v/v, on silica gel plate), water was added,and the product was isolated by extraction with dichloromethane. The organic phase was washed with water, brine, dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum toobtain the desired crude products. The appropriate compounds (2-26) were obtained following purification by silica gel column chromatography with dichloromethane/methanol/triethylamine= 60:1:0.5 (v/v/v).

This mesohemin derivative was synthesized in a manner similar to the previously published method.Mesohemin-MPEG550 (550 mg, 0.630 mmol), 1-(3-aminopropyl)imidazole (158 mg, 1.260mmol), and N-(3-dimethylaminopropyl)-N(ethylcarbodiimide hydrochloride (EDC·HCl) (266mg, 1.390 mmol) and DMAP (8 mg, 0.070 mmol) were mixed in 10 mL of DCM in a smallflask while on ice bath. The reaction mixture was brought to room temperature and stirred for24h. After completion of reaction the solution was washed with 0.1 M HCl (3x10 ml), withsaturated NaHCO3 (2x10 ml), and washed with slightly acidic 1M NaBr, and passed throughshort NaBr column. After that mixture was dried with MgSO4 and solvent was removed underreduced pressure yielding 707 mg of mesohemin-(MPEG550)2 (87 % yield). The finalcompound was analyzed by ESI-MS and UV-Vis. λmax: 401, 496, 518, 567 and 621 nm. m/z[M+Na]+: 981.6 - 1605.4 with interval of 44 (M+).

The vessel was stoppered and stirred at 145°C on an oil bath for 16 hours. The reaction mixture was washed with pH 1 HCI (15 ml_), then water (4x 150 ml_). The organic layer was dried over magnesium sulfate and concentrated in vacuo to give an orange/brown solid (7) (0.883 g, 70 %).

Then, the mixture was cooled down to 0C and sodium triacetoxyborohydride (474 mg, 2.238 mmol, 1.4 eq.) was added in one por- tion. The reaction was allowed to reach rt over 16 h. The reaction mixture was diluted in water and washed with DCM. Aqueous layer was basified with 5N NaOH and extracted with DCM. The layers were separated. Organic layer was dried, filtered off and concentrated to afford the title compound (200 mg, 0.854 mmol, yield 48%) as a transparent oil.
