Thionyl Chloride → Chlorocarbonyl methoxy-acetic acid benzyl ester

Participants

Reaction Steps

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