実験手順

20% palladium hydroxide on carbon powder (102 mg) was suspended in a MeOH (29 ml) solution of tert-butyl rel-(3R,4S)-4-[(benzyloxy)methyl]-3-fluoro-4-methoxypiperidine-1-carboxylate (971 mg), and stirring was performed at room temperature under a flow of hydrogen gas for 4 hours. After filtration through Celite, the filtrate was concentrated to obtain tert-butyl rel-(3R,4S)-3-fluoro-4-(hydroxymethyl)-4-methoxypiperidine-1-carboxylate (800 mg).
