実験手順
(3R)-4-Benzylmorpholine-3-methanol (1.04 g, 5.0 mmol), t-butyldimethylchlorosilane (0.83 g, 5.5 mol), and imidazole (0.41 g, 6.0 mmol) were allowed to react in 5 mL of dichloromethane at room temperature overnight. The reaction product was purified by silica gel column chromatography (hexane:ethyl acetate=5:1) to obtain (3S)-3-(t-butyldimethylsilyloxy)methyl-4-benzylmorpholine (1.53 g, 95%) as a colorless oil.
