Conditions

Temperature: 100 °C

Procedure

8 ml of a 30% sodium methylate solution are added dropwise to 158 g (1 mol) of itaconic acid dimethyl ester and 110 g of dimethyl phosphite at 60° C. The exothermic reaction is by that time completed. The mixture is then stirred for one hour at 100° C. and concentrated by evaporation. Quantitative yield of a colorless liquid.
