Procedure

A mixture of 75 g of (S)-ethyl lactate and 164 g of morpholine was heated at 80° C. for 64 hours. The reaction solution was concentrated and purified by silica gel chromatography (eluent; hexane:ethyl acetate=4:1 to ethyl acetate) to give 69.4 g of 4-[(S)-2-hydroxypropionyl]morpholine as a pale yellow oil.
