Reaction Steps

Ammonia was passed (for 5 min) into a stirred solution of 1-naphthalenesulfonyl chloride (5.0 g, 22 mmol) and anhydrous Et2O (400 ml) at -78°. The resulting mixture was stirred at -78° for 1 hr, allowed to warm to room temperature, and stirred overnight. The Et2O was removed under vacuum to leave a white powder which was washed with water and dried under vacuum to give 3.2 g (70%) of the title compound as a white powder, m.p. 152°-153° C.
