Procedure

A mixture of ethyl 3-chloro-2-phenylpropionate (1 g, 4.72 mmol) prepared in the above (1) and morpholine (470 mg, 5.4 mmol) was stirred to cause reaction for 6 hours under heating at 110° C. To the resulting solution, saturated aqueous sodium bicarbonate was added. After the prepared solution was extracted with ethyl ether, the extract was washed with saturated aqueous sodium chloride, and then dried over anhydrous sodium sulfate. Subsequently, the solvent was removed by distillation under reduced pressure to obtain a crude product. The product was purified by silica gel column chromatography using acetone/hexane=1/6 to obtain 660 mg of the titled compound as a colorless oil (yield: 53.2%).
