Reaktionsschritte

In dichloromethane (150 mL) was dissolved 15.09 g (0.1108 mol) of 2,3,5-trimethylphenol, and 17.82 mL (0.2204 mol) of pyridine, then 20.78 mL (0.2202 mol) of acetic anhydride were added to the solution, and the mixture was stirred at room temperature overnight. The reaction mixture was poured into water, and extracted with dichloro-methane. The organic layer was successively washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was removed, and the residue was purified by silica gel column chromatography (Wako gel C-100, hexane:ethyl acetate, gradient) to obtain 20.08 g (0.1127 mol, Yield: quantitative) of 2,3,5-trimethylphenyl acetate.
