Mon-ethyl methoxy(methyl)malonate (14.52 grams, 0.08 mole) was reacted with thionyl chloride (19.61 grams, 0.16 mole) at 50° C. for a 13-hour reaction period with an additional holding period of approximately 32 hours at room temperature. Vacuum evaporation of the excess thionyl chloride gave 15.2 grams (0.08 mole) of ethyl 2-(chlorocarbonyl)-2-methoxypropionate. NMR analysis of the product indicated the following:
