80%	With hydrogenchloride; iron; In ethanol; water; at 90℃; for 1h;	To a solution of <strong>[349-96-2]4-nitrobenzenesulfonyl fluoride</strong> (1.03 g, 5.00 mmol)in ethanol (60 mL) and water (15 mL) was added conc. hydrochloric acid (3 mL) and iron fillings (1.396 g, 25.00 mmol). The suspension was heated to 90 C for 1 h, cooled and filtered through ashort pad of silica, washing with ethanol (100 mL). The solution was concentrated in vacuo and theresidue extracted between EtOAc (80 mL) and 1M NaOH(aq) (80 mL). The organic layer was driedover MgSO4 and concentrated in vacuo. Purification by column chromatography (20% EtOAc inPetrol) yielded an off white solid (702 mg, 80%).
	With palladium on carbon; hydrogen; acetic acid; In ethyl acetate; for 3h;	To a solution of compound 9a (200.0mg, 0.975mmol) in 10mL EtOAc/ AcOH (1:1) was added 20% Pd/C catalyst (40.0mg). The reaction mixture was stirred under H2 atmosphere for 3h. The reaction mixture was filtered through Celite and the filtrate was evaporated to dryness under vacuum. The residue was dissolved in EtOAc (40mL) and washed with 5% NaHCO3 (10mL×3), H2O (10mL×2) and brine (10mL). The organic layer was dried over Na2SO4, filtered, and evaporated under vacuum to afford the crude aniline derivative, which was used without further purification. To a solution of the above crude aniline derivative and Fmoc-Lys(Boc)-OH (435.5mg, 1.023mmol) in 3mL anhydrous pyridine cooled in an ice/salt bath (-16C) under argon, was added freshly distilled POCl3 (90.6muL, 0.9747mmol). The reaction mixture was stirred for 2.5h, and then diluted with EtOAc (40mL). The EtOAc solution was washed with 5% citric acid (10mL×3), water (10mL×2), and brine (10mL). The organic layer was dried over Na2SO4, filtered, and evaporated. The desired product was purified with silica gel column chromatography eluted with hexane/EtOAc (65/35).

Acta. 43, 1513-1519 (1960) ) was dissolved in water (60 mL) containing 38% HCI (14.4 mL). Thiophosgene (2.7 mL, 36.0 MMOL) was added in one portion. The resultant mixture was stirred rapidly for a half hour, then diluted with water (200 mL). The resultant white precipitate was filtered off, washed with water, and dried under high vacuum to obtain 7.28 G (99%) of white powder, which was used without further purification. 1HNMR (DMSO-D6) : 8 8. 03 (2H, d, J = 9. 3 HZ), 7.44 (2H, d, J = 9. 3 HZ). FABMS: (M-H+) : 216. 2-Bromo-2', 6'-difluoroacetophenone, which has the structural formula was prepared as follows. To a mechanically stirring solution of 2', 6'-difluoroacetophenone (100.0 G, 640.0 mmol ; Melford Laboratories, Ltd. ) in ethyl acetate (1300 mL) were added freshly milled copper (II) bromide (300 G, 1.35 mol) and bromine (1.6 mL, 32 MMOL). The mixture was heated at reflux for 2.25 hours and allowed to cool to ambient temperature. The resultant green mixture was filtered and the solids rinsed with ethyl acetate (4x100 mL). The filtrate was concentrated with a rotary evaporator under reduced pressure, diluted with methyl t-butyl ether (MTBE; 650 mL), filtered through a pad of silica gel (230-400 ; 9.5 cm diam. X4 cm. ht. ), and solids rinsed with MTBE (5x200 mL). Concentration of the filtrate gave a pale green oil, which was purified by fractional vacuum distillation to give 117 g of pale yellow oil, bp 88-97C (2.0 mm Hg) in 78% yield.

The mixture was stirred at ambient temperature for a half-hour, then partitioned between CH2C12 and water, and acidified to pH=4 with 1 N HCI. The organic layer was separated, washed with brine, and dried over NA2SO4. The solvent was evaporated to give a hard foam, which was purified via column chromatography with 1: 1 ethyl acetate (EtOAc) and hexane (hex) as eluant to afford 6.2 G (82% yield) of a yellow powder. 1H NMR (DMSO-D6) : 8 11.50 (1 H, s), 8.35 (2H, bm), 8.10 (2H, d, J = 9.0 Hz), 7.96 (2H, d, J = 9. 0 HZ), 7.58 (1H, m), 7.24 (2H, dd, J = 7. 8,8. 2 HZ).

Solution temperature was kept at about 0 C by an ice bath and protected by an Ar balloon. 175 mg ( l mmol) <strong>[98-62-4]4-aminobenzenesulfonyl fluoride</strong> was dissolved into 1 mL DCM and this solution was added into the flask slowly by syringe over 10 min, followed by 0.14 mL ( 1 eq) Et3N. After the addition, the ice bath was removed and the reaction mixture was stirred at room temperature for 2 hours. (0195) Reaction can be monitored by quenching the solution with methanol, then submitting the sample to LCMS. The solution was concentrated by rotary evaporation, and 4-isocyanato benzenesulfonyl fluoride was obtained as a yellow oil (mixed with Et^N/HCl salt). The isocyanate product can be used as it is, or dissolved in DCM then directly use for next steps. This intermediate is not stable at room temperature as a crude product. A rapid wash with 1M HC1, followed by saturated sodium chloride, and drying over sodium sulfate afforded a material that could be stored for up to one week;. 4-isocyanatobenzenesulfonyl fluoride was obtained as yellow solid.
