Versuchsvorschrift

To a solution of 1,2,6,7-tetrahydro-8H-cyclopenta[d]furo[2,3-b]pyridine-8-ylideneacetonitrile (84.9 mg, 0.428 mmol) in methanol (3 mL) were added Raney cobalt (400 mg) and 2M ammonia/ethanol solution (1.5 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. The obtained title compound was used for the reaction in Example 19 without purification.
