To a solution of 0.35 g (1.89 mmol) of 4-methyl-1-napthoic acid in 3 mL of dry dichloromethane under argon, was added 2.5 ml (34.3 mmol) of thionyl chloride. The solution was refluxed for 4 hrs and the solvent and excess thionyl chloride were removed by vacuum distillation to give a red oil, which was used without further purification.
