Procedure
Ex-35A: To a solution of 4-acetylbenzenesulfonyl chloride in acetone (30 mL) was added ammonia (28% in water, 8.2 mL, 57.3 mmol) dropwise at 0° C. The reaction mixture was allowed to stir at 0° C. for 30 min. The precipitate was filtered and the residue was washed with water and dried in vacuo to afford 4-acetylbenzenesulfonamide as a white solid (3.54 g, 93%), mp 176–177° C. 1H NMR (DMSO-d6) δ 8.10 (d, J=9 Hz, 2H), 8.03 (d, J=9 Hz, 2H), 4.86 (brs, 2H), 2.65 (s, 3H). HRMS Calcd. for C8H9NO3S: 199.0303 (M+); Found: 199.0300.
