Procedure

0.65 g of 2-isopropyl-8-methyl-1-naphthol was dissolved in 50 ml of dichloromethane and cooled down to 0° C. 1.3 ml of titanium tetrachloride was gradually dropped in the solution for reaction at 0° C. for 5 minutes, after which 0.9 ml of dichloromethyl methyl ether was gradually dropped and reacted at 0° C. for 1 hour. Water was added to the reaction solution, which was extracted with ethyl acetate. The resultant organic phase was washed with a saturated saline solution, dried with anhydrous magnesium sulfate and concentrated under reduced pressure. The resulting crystals were collected by filtration to obtain 0.7 g of the captioned compound as black crystals.
