Reaction Steps
To 370 mg (1.02 mmol) of 4-(2-cyano-5-methoxy-3-nitro-phenyl)-piperazine-1-carboxylic acid tert-butyl ester dissolved in 5 mL ethanol and 5 mL ethyl acetate was added a pipet of Raney nickel slurry in water followed by 64 μL (2 eq., 2.04 mmol) hydrazine. The mixture was stirred 30 minutes to completion, filtered through Celite and concentrated under reduced pressure to provide 300 mg of crude 4-(3-amino-2-cyano-5-methoxy-phenyl)-piperazine-1-carboxylic acid tert-butyl ester.
