Reaction Steps

[Step 3] To a mixture of 4-ethanesulfonylbenzonitrile (500 mg) in methanol (6 ml) and tetrahydrofuran (2 ml) was added 28% aqueous ammonia (1 ml) and then Raney nickel (500 mg) was added. Under a hydrogen pressure (0.5 Mpa), the mixture was stirred at room temperature for 2 hrs., and undesired substances were removed by filtration. The filtrate was concentrated under reduced pressure to give 4-ethanesulfonylbenzylamine (408 mg, 82%).
