Water → Benzyl (3-oxomorpholin-4-yl)acetate

Participants

Reaction Steps

Under an argon atmosphere, to a solution of morpholin-3-one (220 mg, 2.2 mmol) in N,N-dimethylformamide (2.2 ml) was added sodium hydride (105 mg, 2.6 mmol) under ice-cooling, and the mixture was stirred for 1 hr. Then, benzyl bromoacetate (379 μl, 2.4 mmol) was added, and the mixture was stirred for 2 hr. To the reaction solution were added water and ethyl acetate, and the organic layer was separated. The aqueous layer was extracted twice with ethyl acetate, and the combined organic layers were washed successively with water and saturated brine, and dried over sodium sulfate. Sodium sulfate was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography to give the title compound (321 mg, yield 59%).
