Reaction Steps

A solution of lithium hydroxide monohydrate (0.106 g) in water (1 ml) was added to a stirred solution of N-[2-chloro-4-(4-acetamidophenylsulphonyl)phenyl]-2-acetoxy-2-methylpropanamide (Method 16) (0.230 g) in methanol (2 ml) and the mixture was stirred at ambient temperature for 2 hours. Water (5 ml) was added and the solution was acidified to pH 2-3 with 1M hydrochloric acid. Ethyl acetate (20 ml) was added and the organic layer was washed with water (20 ml) and brine, then dried. Volatile material was removed by evaporation and the off-white solid was washed with ether to give the title compound (0.150 g) as a solid. NMR (CDCl3): 1.3 (s, 6H), 2.2 (s, 3H), 7.4 (s, 1 H), 7.7 (d, 2H), 7.8 (m, 3H), 7.9 (s, 1H), 8.7 (d, 1H), 9.6 (s, 1H); MS (ESP−): 409.
