実験手順: To a solution of tert-butyl morpholin-2-ylmethylcarbamate (0.50 g) in dichloromethane (5 mL) was added oxetan-3-one (0.20 g). After stirring for 5 minutes, sodium triacetoxyborohydride (0.735 g) was added. After stirring for 2 hours, the reaction was diluted with dichloromethane (50 mL) and quenched with saturated NaHCO3 solution (50 mL). The organic layer was separated, washed with brine (40 mL), dried over magnesium sulfate, filtered, and concentrated. Silica gel chromatography (Reveleris 80 g) eluting with a gradient of 0.5% to 5% methanol/dichloromethane over 40 minutes (flow=40 ml/minute) gave the title compound. After stirring for 2 hours quenched with saturated NaHCO3 solution (50 mL) The organic layer was separated washed with brine (40 mL) dried over magnesium sulfate filtered concentrated Silica gel chromatography (Reveleris 80 g) eluting with a gradient of 0.5% to 5% methanol/dichloromethane over 40 minutes (flow=40 ml/minute)
