HCID 834001-Chloro-3-[chloro(phenyl)methyl]benzeneYield 37%

Procedure

A solution of (3-chlorophenyl)(phenyl)methanol (500 mg, 2.3 mmol) in thionyl chloride (3 mL) was stirred at 80° C. for 16 h. After cooling to room temperature, the reaction mixture was concentrated and purified by silica gel column (eluting with petroleum ether/ethyl acetate=100/1) to give the desired product (200 mg, 37%) as yellow oil.
