Методика

A solution of 715 mg (2.4 mmol) of tert-butyl 2-methyl-6-nitro-3-oxo-2,3-dihydro-1H-indazole-1-carboxylate in 30 ml of ethanol was hydrogenated in the presence of 52 mg of palladium (10% on activated carbon) at RT and standard pressure. The reaction mixture was then filtered through Celite and the filtrate was concentrated under reduced pressure and dried. Yield: 668 mg (100% of theory)
