Procedure

To a solution of bis(4-chlorophenyl)methanol (2.0 g) in dichloromethane (20 ml) was added oxalylchloride (1 ml). The mixture was stirred for 4 hours and the solvent was removed in vacuo. The residue was dissolved in n-hexane (20 ml) and filtered off. The solvent was removed in vacuo to give colorless oil of bis(4-chlorophenyl)methyl chloride (2.15 g).
