Versuchsvorschrift

20 ml of ethanethiol was added to 100 ml of a suspension of 28 g of aluminium chloride in dichloromethane cooled with ice. The obtained mixture was stirred for 5 minutes, followed by the slowly, dropwise addition thereto of 50 ml of a solution of 15.3 g of 6-isopropyl-7-methoxy-1-tetralone in dichloromethane. After the completion of the dropwise addition, the obtained mixture was stirred for 3 hours at room temperature and poured onto ice-water. The obtained mixture was extracted with ethyl acetate. The organic phase was washed with water, a saturated aqueous solution of sodium hydrogencarbonate and a saturated aqueous solution of common salt successively, dried over anhydrous magnesium sulfate, and distilled to remove the solvent. The obtained solid residue was washed with n-hexane to give 8.5 g of the title compound as a white solid.
