Participants

Reaction Steps

A solution of 4-(4-methoxyphenyl)-4-methyltetrahydro-2H-pyran (0.518 g, 2.51 mmol) in dichloromethane (12.0 mL) was cooled to −15° C., and titanium tetrachloride (1.22 mL, 11.0 mmol) was added dropwise thereto. After stirring the mixture for 20 minutes, dichloromethyl methyl ether (0.336 mL, 3.77 mmol) was added dropwise thereto. After stirring the mixture for 1 hour, 1 mol/L hydrochloric acid was added to stop the reaction. The reaction solution was diluted with ethyl acetate, and the organic layer was washed with water and then with saturated brine, dried over anhydrous sodium sulfate and filtered. The solvent was then evaporated under reduced pressure to obtain 0.719 g of the crude product containing the captioned compound.
