Reaction Steps

Ex-29A: To a solution of 4-acetylbenzenesulfonyl chloride (1.1 g, 5.0 mmol) in 25 ml of THF, methylamine (0.44 ml of 40% solution in H2O, 5 mmol) was added dropwise, and the mixture was stirred for 30 min. The reaction mixture was poured into water, and the precipitate was filtered. Recrystallization from EtOAc/hexanes gave 0.67 g (62.6%) of 4-acetyl-N-methyl-benzenesulfonamide as a white solid. 1H-NMR (300 MHz, CDCl3) δ 8.09 (d, J=8 Hz, 2H), 7.96 (d, J=8 Hz, 2H), 4.48 (br, 1H), 2.70 (d, J=4 Hz, 1H), 2.66 (s, 3H).
