Procedure
650 μl (8.8 mmol) of thionyl chloride was added dropwise to a stirred solution of 1 g (5.8 mmol) of 3-(chloromethyl)benzoic acid in 40 ml of methanol at 0° C. under a nitrogen atmosphere, then stirred at room temperature overnight. The solvent was evaporated, the residue dissolved in dichloromethane (30 ml), washed with saturated aqueous sodium bicarbonate (2×40 ml), brine (40 ml), dried over magnesium sulfate, filtered and evaporated to give 0.94 g (88%) of methyl-3-(chloromethyl)benzoate as a colorless mobile liquid.
