Procedure

A solution of 3-hydroxymethyl-4,4'-dimethylbiphenyl (1.3 g) and triethylamine (0.8 g) in methylene chloride (50 ml) was cooled to 0° C., and methanesulfonyl chloride (0.84 g) in methylene chloride was added dropwise. The mixture was allowed to warm to room temperature, and was stirred overnight. Ice/water was then added, the organic layer separated, the aqueous layer washed with methylene chloride, the organic layer washed with brine, dried over sodium sulfate, and the solvent evaporated under reduced pressure, to yield 3-chloromethyl-4,4'-dimethylbiphenyl as an oil.
