To a solution of 2.54 g of tert-butyl 1,2,3,6-tetrahydro-4-(3-nitrophenyl)pyridine-1-carboxylate (which was prepared by the method as described in Synthesis, 1991, 993-995) in 20 ml of methanol, 250 mg of 10% palladium-on-carbon catalyst was added, and stirred for an hour in hydrogen atmosphere at ambient temperature and pressure. After addition of 20 ml of tetrahydrofuran to the reaction liquid, the liquid was filtered with Celite. Distilling the solvent off under reduced pressure, 2.30 g of the title compound was obtained.
