반응 단계

In 50 ml of toluene were dissolved 7.31 g (0.05 mole) of monomethylglutaric acid, 4.43 g (0.085 mole) of furan and 14.39 g (0.06 mole) of dichloroacetic anhydride. To the resulting solution was added 0.71 g of boron trifluoride-diethyl ether complex and the resulting mixture was then stirred at 50° C. for 3 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 and the resulting concentrated residue was then purified by silica gel-filled column chromatography to obtain 9.54 g of 2-(4-methoxycarbonylbutyryl)furan.
