Reaction Conditions:
with propionic acid in toluene
Steps:
33 EXAMPLE 33
EXAMPLE 33 In 50 ml of toluene were dissolved 3.7 g (0.05 mole) of propionic acid and 10.26 g (0.06 mole) of monochloroacetic anhydride. To the resulting solution were added 5.36 g (0.065 mole) of 2-methylfuran 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 and the resulting concentrated residue was then purified by silica gel-filled column chromatography to obtain 2.96 g of 2-propionylfuran. Yield: 42.8% nD25: 1.5078
