Reaction Steps

To a solution of (8-hydroxy-7-isopropyl-1,6,7,8-tetrahydro-2H-cyclopenta[d]furo[2,3-b]pyridin-8-yl)acetonitrile (440 mg, 1.70 mmol) in ethanol (12 mL) were added Raney cobalt (4 g) and 2M ammonia/ethanol solution (6 mL), and the mixture was stirred at room temperature for 4 hr under a hydrogen atmosphere. The catalyst was filtered through celite, and the filtrate was concentrated under reduced pressure to give the title compound (446 mg, yield 100%).
