Procedure

A mixture of 3-(4-biphenylyl)propionic acid (5 g, 22.10 mmol) and SOCl2 (4.03 ml, 55.2 mmol) is refluxed under nitrogen at 85° C. for 1.5 hour. The reaction mixture is concentrated under reduced pressure to give 3-(biphenyl-4-yl)propanoyl chloride (5.46 g). The material is used in the next step without further purification.
