[2-(Dibenzylamino)-5,6-dihydro-7H-cyclopenta[b]pyridin-7-ylidene]acetonitrile (1.01 g, 2.87 mmol) was dissolved in methanol (40 mL), 20% palladium hydroxide-carbon powder (200 mg) was added, and the mixture was stirred under a hydrogen atmosphere at room temperature for 60 hr. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound. The obtained title compound was used for the reaction of Reference Example 34 without purification.
