Reaction Steps
8,9-Dihydrofuro[3,2-c]pyrazolo[1,5-a]pyridin-1-ylacetonitrile (250 mg, 1.25 mmol) and Raney cobalt (2.5 g) were suspended in 2M ammonia/methanol solution (50 mL), and the suspension was stirred at room temperature for 12 hr under a hydrogen atmosphere. The catalyst was filtered through celite, and the filtrate was concentrated under reduced pressure to give the title compound (238 mg, yield 94%).
