反応手順

About 600 ml of a 1.5M solution of methyllithium in ether was added to 500 ml of tetrahydrofuran to obtain a mixture. A suspension of 93.45 g of 5-acetyl-1,3-benzodioxole in 900 ml of tetrahydrofuran was added to the mixture, while keeping it at -20° C. by cooling and the obtained mixture was stirred as such for one hour. Water was added to the reaction mixture and the obtained mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of common salt and dried over anhydrous magnesium sulfate. The resulting mixture was filtered and the filtrate was concentrated to obtain 97 g of the title compound as an oil.
