Reaction Steps

An Et2O (25 ml) solution of tert-butyl 6-[(benzyloxy)methyl]-7-oxa-3-azabicyclo[4.1.0]heptane-3-carboxylate (3.37 g) was added dropwise under ice-cooling to an suspension of LAH (520 mg) in Et2O (75 ml), and was stirred at room temperature for 1 hour, Under ice-cooling, a saturated ammonia aqueous solution (1 ml) was added. After dilution with THF, stirring was performed at room temperature for 2 hours. After drying over anhydrous magnesium sulfate, Celite filtering was performed. The residue obtained by concentration was purified by silica gel column chromatography (EtOAc/hexane) to obtain tert-butyl 4-[(benzyloxy)methyl]-4-hydroxypiperidine-1-carboxylate (2.59 g).
