YieldReaction ConditionsOperation in experiment
13 g With sodium hydrogencarbonate In N,N-dimethyl-formamide at 25 - 30℃; 20 g of ethyl 2-chloro-2-(hydroxyimino)acetateprepared above, 23 g of 1,1-diphenylethylene, 100 ml of DMF, and put into 22 g of sodium hydrogencarbonate, and maintained at 25 ° C to 30 ° C for 6-8 h. After the reaction is completed, the mother liquor is obtained by suction filtration, DMF is recovered by vacuum distillation, and then washed with 100 ml of water, heated to 40 ° C - 50 ° C, and the lower oil layer is separated, stirred with 20 ml of triethylamine, cooled to 10 ° C - 15 ° C, and filtered. The product was obtained in an amount of 13 g and a content of 99.5percent.

YieldReaction ConditionsOperation in experiment
12.7 g With triethylamine In diethyl ether for 2 h; 13.52 g (0.075 mol) of 1,1-diphenylethene and 5.06 g(0.05 mol) of triethylamine are dissolved in 200 ml of etherat 0° C., and 7.58 g (0.05 mol) of ethyl 2-chioro-2-hydroxi-minoacetate, dissolved in 100 ml of ether, are subsequentlyadded dropwise in the course of approximately two hours.Afier stirring has been continued for one hour at roomtemperature, 100 ml of H20 are added, and the mixture issubsequently extracted using ethet After drying over aMg504, the ether is distilled off and the residue is purifiedover a silica gel colunm (eluent: n-heptane:ethyl acetate=8:2). In this way, 12.7 g of product of melting point 78° C. to81° C. are obtained.As shown in FIG. 4, the X-ray powder diffraction patternof the resulting isoxadifen-ethyl products prepared abovehas no significant signals, which indicates the isoxadifen35 ethyl product prepared in accordance with the disclosure ofU.S. Pat. No. 5,516,750 is amorphous.
