To a solution of (2-methyl-6,7-dihydrocyclopenta[e]indazol-8(2H)-ylidene)acetonitrile (600 mg, 2.87 mmol) in ethanol (14 mL) were added Raney cobalt (6 g) and 2M ammonia/ethanol solution (14 mL), and the mixture was stirred under a hydrogen atmosphere at room temperature for 3 hr. The catalyst was filtered off through celite, and the filtrate was concentrated under reduced pressure to give the title compound (614 mg, yield 99%).
