실험 절차

26 g (186 mmol) of methyl chloromethoxyacetate and 32 mL (186 mmol) of triethyl phosphite are placed in a round-bottomed flask and heated at 150° C. for 3 hours. The reaction progress is monitored by NMR. The reaction medium is concentrated under vacuum. 45 g (100%) of methyl (diethoxyphosphoryl)methoxyacetate are obtained directly in the form of a colorless liquid.
