Reaction Steps

To a solution of N-{2-[(3-aminobenzyl)sulfanyl]-5-chlorophenyl}-1-benzofuran-2-sulfonamide (440 mg, 0.90 mmol) in CH2Cl2 (10 ml) was added acetyl chloride (71 μl, 0.99 mmol), pyridine (180 μl, 2.25 mmol), and catalytic amount of DMAP. The reaction was stirred at room temperature for 2 hours, diluted with 1M HCl, and extracted with CH2Cl2. The organic layer was dried over Na2SO4, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (5-10% EtOAc in hexane) to yield the title compound (330 mg, 68%).
