Acetic Acid → HCID 67163670, compound

Participants

Reaction Steps

In a mixture of 10 mL of water, 2 mL of acetic acid and 0.52 g of reduced iron, a solution of 0.84 g of 4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazole-3-yl]-2-nitro benzoic acid amide in 10 mL of ethyl acetate was added dropwise at 75° C. with stirring. After the completion of the addition dropwise, it was stirred at the same temperature further for 2.5 hours. After the completion of the reaction, insoluble material was removed by hot filtration, 20 ml of water was added in the filtrate, and the organic phase was collected, and the aqueous phase was extracted with ethyl acetate (10 ml×2). The combined organic phases were washed with 10 ml of saturated sodium hydrogen carbonate aqueous solution, and then dehydrated with and dried over saturated sodium chloride aqueous solution and then anhydrous sodium sulfate, and then the solvent was distilled off under reduced pressure to obtain 0.80 g of the crude aimed product as yellow crystal. The resulting product was used as such without purification for the next step.
