Reaction Steps

A solution of 5.1 g of 3-(3'-p-chlorobenzoyl-2'-methoxy-phenyl)-propionic acid in 25 ml of thionyl chloride was refluxed for 21/2 hours and the excess thionyl chloride was distilled off. The residue was taken up in benzene and was evaporated to dryness to obtain 5.6 g of 3-(3'-p-chlorobenzoyl-2'-methoxy-phenyl)-propionyl chloride which was used as is for the next step.
