Reaction Steps

A mixture consisting of 12.62 g of 2,4-difluoro-6-nitrophenol, 36 ml of epichlorohydrin, 3.3 g of sodium hydroxide, 15 ml of water and 320 ml of ethanol was stirred at 80° C. for 24 hours. After cooling the reaction solution to room temperature, the insoluble matter was removed by filtration and the filtrate was concentrated to dryness under a reduced pressure. The resulting residue was dissolved in an ether-hexane (1:2) mixed solvent, washed with water and saturated brine and dried with anhydrous sodium sulfate, and then the solvent was evaporated under a reduced pressure. The residue was applied to a silica gel column chromatography and developed with an ethyl acetate-hexane (1:9) mixed solvent, and then the fractions containing the compound of interest were concentrated to obtain 11.28 g of the title compound.
