Peracetic Acid → HCID 53723907, Verbindung

A mixture of 1.1 g of 3-(N-methyl-N-styrylsulfonylamino)-2-(6-trifluoromethylpyridin-2-yl)propene, 0.20 g of sodium acetate trihydrate, 2.19 g of 40% peracetic acid and 11 ml of chloroform was stirred at 60° C. for 5 hours. After the reaction mixture was cooled to room temperature, 10 ml of carbon tetrachrolide was added thereto, and the whole mixture was subsequently washed with water, an aqueous solution of 10% sodium bisulfite, a 2N aqueous solution of sodium hydroxide, water and saturated saline solution in that order and dried over anhydrous magnesium sulfate. After the solvent was distilled off, the residue was purified by silica gel column chromatography (eluted with benzene-ethyl acetate 15:1) to obtain 0.70 g of Compound No. 4 in Table 1.
