反応手順

Into a 100 mL round bottom flask was added ethyl 1-((6-((4-(tert-butyl)cyclohexylidene)methyl)naphthalen-2-yl)methyl)piperidine-4-carboxylate (200 mg, 0.45 mmol), Pd/C (20%, 20 mg) and THF (30 mL). The reaction mixture was flushed 3 times with hydrogen gas and stirred for 48 h under H2 atmosphere. The reaction mixture was filtered and the filtrate was concentrated in vacuum to afford the desired compound ethyl 1-((6-((4-(tert-butyl)cyclohexyl)methyl)naphthalen-2-yl)methyl)piperidine-4-carboxylate as purple oil (150 mg, yield: 30%). ESI-MS (M+1)+: 450.3.
