Versuchsvorschrift

To a mixture of 3-(4-tert-butyl-cyclohexyloxy)-1-methyl-naphthalene (450 mg, 1.5 mmol) in 1,2-dichloroethane (9 mL) was added tin tetrachloride (236 uL, 2 mmol) at 0° C. After stirred at 0° C. for 1 hr, dichloromethyl methyl ether (183 uL, 2 mmol) was added. The solution was stirred at 0° C. for 1 hr and then warmed to room temperature. The mixture was added ice water and stirred for 1 hr, then the dark solution was diluted with dichloromethane and washed with water. The organic phase was washed with sodium bicarbonate aqueous, and dried over MgSO4. The driving agent was filtered off and the solvent was concentrated to dryness to give dark solid product (0.48 g, yield: 97%). ESI-MS: 325.20 (M+H)+.
