Procedure

An amount of 10.6 g (86 mmol) of trimethyl phosphite was added dropwise to 20.0 g (86 mmol) of p-chlorophenoxyisobutyryl chloride cooled to 0° C. As verification of the reaction, evolution of methyl chloride could be observed. Distillation under reduced pressure gave 19.0 g (62 mmol) of dimethyl p-chlorophenoxyisobutyrylphosphonate as an almost colorless oil.
