Reaction Conditions

Reaction Steps

In 50 ml of toluene were dissolved 4.31 g (0.05 mole) of crotonic acid, 4.43 g (0.065 mole) of furan and 10.26 g (0.06 mole) of monochloroacetic anhydride. To the resulting solution was added 0.71 g of boron trifluoridediethyl ether complex and the resulting mixture was then stirred at 50° C. for 6.5 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 concentrated under reduced pressure and the resulting concentrated residue was then purified by silica gel-filled column chromatography to obtain 2.8 g of 2-crotonylfuran.
