반응 단계

In 50 ml of dichloroethane were dissolved 8.51 g (0.05 mole) of 4-(2-thienyl)butyric acid and 14.39 g (0.06 mole) of dichloroacetic anhydride. To the resulting solution was added 0.065 mole of 3,5-dimethylfuran and 0.71 g of boron trifluoride-diethyl ether complex and the resulting mixture was then stirred at 50° C. for 7 hours. After completion of the reaction, the reaction solution was cooled and washed successively with 5% aqueous sodium carbonate solution and water. The organic layer was concentrated under reduced pressure to obtain 2-[4-(2-thienyl)butyryl]3,5-dimethylfuran.
