To a solution of 5 g of succinic acid monobenzyl ester in 60 ml of benzene was added 11 ml of oxalyl chloride. After 5 hrs at 20° C., gas evolution ceased and the solvent and excess oxalyl chloride was evaporated at 20° C. The residue was held at 1 torr for 1 hr to yield 5.19 g of crude benzyl 3-chloroformylpropionate; ir 1788 and 1735 cm-1.
