Procedure
To a stirred solution of morpholine (479 mg, 5.5 mmol, 1.1 eq) and triethylamine (1.01 g, 10 mmol, 10 eq) in DCM (20 mL) at 0° C., ethyl 3-chloro-3-oxopropanoate (750 mg, 5 mmol, 1.0 eq) was added and the resulting mixture was stirred at RT for 1 h. The reaction mixture was poured into water (50 mL) and extracted with ethyl acetate (3×50 mL). The combined organic layers were washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by flash column chromatography on silica gel (1-50% ethyl acetate-hexanes) to afford the product ethyl 3-morpholino-3-oxopropanoate 33.
