Procedure
A mixture of 445 mg (0.960 mmol) [2,2-dimethyl-4-(3-methylamino-4-nitro-benzoyl)-piperazin-1-yl]-(1-phenyl-1H-[1,2,4]-triazol-3-yl)-methanone and 300 mg Raney nickel in 50 mL MeOH was hydrogenated at RT for 7.5 h. The catalyst was removed by filtration and the solvent was evaporated in vacuo.
