2-Acetylbenzofuran → 1-(1-Benzofuran-2-Yl)-2-Bromoethan-1-One

Participants

Reaction Steps

Benzofuran-2-yl methyl ketone (20 g) is dissolved in 100 ml of methylene chloride and 3.2 ml of bromine in methylene chloride is added at 5°-10° C. Then the reaction mixture is stirred at +15° C. for 2 hours. Then it is washed with water, with diluted sodium bicarbonate solution and again with water. The organic phase is dried and evaporated to dryness to give crude 1-(benzofuran-2-yl)-2-bromoethanone.
