Conditions

Temperature: 0 °C

Procedure

To a solution of 27.3 g of 4-benzyloxy-3-chloro-5-methylphenol dissolved in 250 ml of chloroform and being stirred at 0° C. were added 15.4 g of benzoyl chloride and then 13.3 g of triethylamine. After stirring at room temperature for 2 hours, the chloroform layer was washed with water, dried with anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel chromatography, which afforded 35 g of 4-benzyloxy-3-chloro-5-methyl-1-benzoyloxybenzene (90% yield).
