HCID 86669389Chlorocarbonyl methoxy-acetic acid benzyl ester

Procedure

A solution of Benzyloxy carbonyl methoxy-acetic acid (40 g) and Thionyl chloride (80 ml) was stirred at reflux temperature for 3 hours. Excess Thionyl chloride was distilled off, to the residue was added toluene (100 ml) and distilled off the solvent completely to get chloro carbonyl methoxy-acetic acid benzyl ester (40 g) as a light brown liquid which was used without further purification.
