Versuchsvorschrift

Then, 25 g of 4-benzoyloxy-2-chloro-6-methylphenol was dissolved in 250 ml of chloroform, to which 12 g of chloromethyl methyl ether was added, while stirring at 0° C., and 21 g of N-ethyldiisopropylamine was added dropwise. After heating under reflux for 1 hour, the chloroform layer was washed with water, and concentrated. The residue was subjected to silica gel chromatography, which afforded 27.4 g of 3-chloro4-methoxymethoxy-5-methyl-1-benzoyloxybenzene (96% yield).
