实验步骤: (Step 3) To a solution of 5-chloro-2-(methylsulfonyl)benzonitrile obtained in Step 2 (3.8 g) in ethanol (25 ml) was added an 8N solution of ammonia in methanol (5 ml) and Raney cobalt (19 g, wet). The resulting mixture was stirred overnight at room temperature under a hydrogen atmosphere. The reaction mixture was filtered through celite, and the filtrate was concentrated under reduced pressure. To the residue were added ethanol (10 ml) and a 2 M hydrogen chloride-methanol solution (10 ml). The resulting mixture was concentrated under reduced pressure, and the residual solid was collected by filtration and washed with ethyl acetate to give 1-[5-chloro-2-(methylsulfonyl)phenyl]methanamine hydrochloride (3.6 g) as a white solid. The reaction mixture was filtered through celite the filtrate was concentrated under reduced pressure To the residue were added ethanol (10 ml) The resulting mixture was concentrated under reduced pressure the residual solid was collected by filtration washed with ethyl acetate
