실험 절차

To a suspended toluene (2 ml) solution of 2-chloro-1-methylpyridinium iodide (306 mg, 1.2 mmol) was added a mixture of benzyl alcohol (108 mg, 1.0 mmol), pivalic acid (102 mg, 1.0 mmol) and tri-n-butylamine (444 mg, 2.4 mmol) in toluene (2 ml), 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 pivalate was isolated in 62% yield.
