Tert-butyl 4-(4-nitrophenoxy)piperidine-1-carboxylate → tert-Butyl 4-(4-aminophenoxy)piperidine-1-carboxylate

Participants

Reaction Steps

2.74 g (8.5 mmol) of 1-t-butoxycarbonyl-4-(4-nitrophenoxy)piperidine was dissolved in 20 ml of ethanol. 20 mg of 10% palladium/carbon was added to the solution, and they were stirred at room temperature in 1 atm. hydrogen atmosphere for 3 hours. Palladium/carbon was removed by the suction filtration. The filtrate was once concentrated and then treated with dichloromethane as extractant in an ordinary manner to obtain the title compound.
