반응 단계

In 50 ml of dichloroethane were dissolved 9.41 g (0.05 mole) of suberic acid monomethyl ester and 9.83 g (0.0575 mole) of monochloroacetic anhydride. To the resulting solution were added 5.47 g (0.065 mole) of thiophene and 0.71 g of boron trifluoride-diethyl ether complex and the resulting mixture was then stirred at 60° C. for 5 hours. After completion of the reaction, the reaction solution was cooled and washed successively with water, 5% aqueous sodium carbonate solution and water. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to obtain 11.5 g of 2-(7-methoxycarbonyl-1-oxoheptyl)thiophene.
