Procedure

To a CH2Cl2 (2 ml) solution of 2-chloro-1-methylpyridinium p-toluenesulfonate (720 mg, 2.4 mmol) was added a mixture of benzyl alcohol (216 mg, 2.0 mmol), benzoic acid (244 mg, 2.0 mmol) and tri-n-butylamine (888 mg, 4.8 mmol) in CH2Cl2, and the resulting mixture was refluxed for 3 hours. After evaporation of the solvent, the residue was separated by silica gel column chromatography, and benzyl benzoate was isolated in 83% yield.
