To a solution of 2.0 g of 1-tert-butyl 4-ethyl 4-(3-(benzyloxy)propyl)piperidine-1,4-dicarboxylate in 20 mL of ethanol, a suspension of 0.30 g of 10% palladium carbon in 2 mL of ethanol was added, and the mixture was stirred for 4 hours under a hydrogen atmosphere. The insoluble substance was filtered off, and the solvent was distilled off under reduced pressure to obtain 1.7 g of 1-tert-butyl 4-ethyl 4-(3-hydroxypropyl)piperidine-1,4-dicarboxylate as a colorless oily substance.
