Procedure

830 mg of 3-(3'-p-chlorobenzoyl-2'-methyl-phenyl)-propionic acid and 4.2 ml of thionyl chloride were refluxed for 3 hours and then excess thionyl chloride was distilled off and the last traces were removed by entrainment with benzene to obtain 876 mg of 3-(3'-p-chlorobenzoyl-2'-methyl-phenyl)-propionyl chloride which was used as is for the next step.

Workup

  1. distillationexcess thionyl chloride was distilled off
  2. customthe last traces were removed by entrainment with benzene
