Procedure

To a solution of 5-methoxy-benzo[b]thiophene-3-sulfonyl chloride(0.80 g, 3.08 mmol) in THF (20 mL) was added ammonia gas until saturation at ca. 10° C., then the flask was stoppered, and the reaction mixture was stirred at rt for 4 h. The reaction mixture was then quenched with water; the organic solvent was slowly evaporated under vacuum. The precipitate formed was filtered off, washed with water and dried over P2O5 under high vacuum to obtain the desired compound (0.64 g) as a yellowish solid. MS (ISN): m/e 239.4 (M−H)−
