Reaktionsschritte

Ex-30A: To a solution of 4-acetylbenzenesulfonyl chloride (2.18 g, 10.0 mmol) in 100 ml of THF at 0° C., Et3N (2.5 g, 25 mmol) was added followed by O-methyl hydroxyamine hydrochloride (0.84 g, 10 mmol). The mixture was stirred for 1 hr at room temperature and then poured into water, and the precipitate was filtered and dried. Recrystallization from THF/hexanes gave 1.5 g (65.8%) of 4-acetyl-N-methoxybenzenesulfonamide as a white solid. 1H-NMR (300 MHz, CDCl3) δ 8.10 (d, J=8 Hz, 2H), 8.03 (d, J=8 Hz, 2H), 7.23 (brs, 1H), 3.82 (s, 3H), 2.66 (s, 3H).
