YieldReaction ConditionsOperation in experiment
45% With aluminum (III) chloride; In nitrobenzene; at 65℃; for 6h; To a solution of dihydroimidazolone 1a (1.0 g, 11.9 mmol) in 24 mL 1M AlCl3 in nitrobenzene was added 2-nitrobenzoyl chloride (2.2 g, 11.9 mmol), and the reaction was heated in a 65° C. oil bath for 6 h. The reaction was poured over ice during which a solid formed. The reaction was filtered through a sintered glass funnel and the solid washed with water and diethyl ether and dried in vacuum dessicator to give 1.26 g (45percent yield) of 4-nitrobenzoyl-1,3-dihydroimidazol-2-one 1b.

A. , Tet. Lett. 1981, 22,2063-2066), potassium carbonate (53 mg, 0.384 MMOL), copper (I) iodide (244 mg, 1.28 MMOL) and N, N'-dimethyl-1, 2-ethanediamine (163 CL, 135 mg, 1.536 MMOL) and dioxane (2.5 mL) was heated at 150°C for 90 min under microwave irradiation. The mixture was cooled to room temperature and partitioned between water and ethyl acetate. The organic layer was dried over magnesium sulfate and concentrated under reduced pressure. The crude compound was purified by flash chromatography on silica gel, eluting with DICHLOROMETHANE-METHANOL (97: 3) affording the title compound in 20percent yield (23mg). The free base was converted into its DIHYDROCHLORIDE salt by dissolving the compound in DICHLOROMETHANE and adding a 1 M ethereal solution of HCI (2.1 eq) dropwise. A yellow solid precipitated and the suspension was stirred for 15 min. The solvent was removed under reduced pressure; the residue was triturated with ether. The title compound was then recovered by filtration (yield quantitative).

The reaction mixture was stirred for 30 minutes. Intermediate 1 (2.69 g) was added portionwise and the resulting reaction mixture was stirred for 16 hours at RT, then for 2 hours at 50° C. The reaction mixture was stirred in methyl isobutyl ketone (200 ml)/(50 ml) water. The solvent was evaporated and methyl isobutyl ketone (100 ml) was added and azeotroped on the rotary evaporator. The mixture was purified by column chromatography over silica gel (eluent: CH2 Cl2 /(CH3 OH/NH3) 97/3). The desired fractions were collected and the solvent was evaporated. The white solid was stirred in diisopropyl ether, filtered off, washed with diisopropyl ether and dried, yielding 0.4 g (12.6percent) of 1-[2-[3-(cyclopentyloxy)-4-methoxyphenyl]-2-oxoethyl]-1,3-dihydro-2H-imidazol-2-one (comp. 1; mp. 201.1° C.).
