実験手順

To a suspended CH2Cl2 (2 ml) solution of 2-bromo-1-methylpyridinium (720 mg, 2.4 mmol) was added a mixture of cinnamyl alcohol (268 mg, 2.0 mmol), acetic acid (120 mg, 2.0 mmol) and tri-n-butylamine (888 mg, 4.8 mmol) in CH2Cl2 (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 cinnamyl acetate was isolated in 82% yield.
