反応手順

15 ml of tetrahydrofuran and a catalytic amount of iodine were added to 340 mg of magnesium ribbon to obtain a mixture. 1.59 g of bromoethane was gradually added to the mixture in a stream of nitrogen in such a way that the reaction system was mildly refluxed. The resulting mixture was heated under reflux for 30 minutes and cooled, followed by the addition of a solution of 2 g of 5 -acetyl-1,3-benzodioxole in tetrahydrofuran. The obtained mixture was stirred at a room temperature for 20 minutes, followed by the addition of a saturated aqueous solution of ammonium chloride and water. The obtained mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of common salt, dried over ahydrous magnesium sulfate and filtered. The filtrate was distilled to remove the solvent. 2.27 g of the title compound was obtained as a crude oil.
