Participants

Reaction Steps

To a 100 ml volume four-necked flask, 4-(2,4,6-triethylphenyl)-2-methyl-5-methylsulfanyl-6-trifluoromethyl-2,3-dihydro-3-pyridazinone ((2-46)-(1)-40) (0.683 g) and chloroform (24 ml) were added at room temperature, and stirred. Sodium hydrogen carbonate (0.597 g), and meta-chlorobenzoic acid (0.615 g) was added and the resulting mixture was stirred at room temperature for 4 hours. Then, the reaction mixture was poured into water (30 ml), added sodium sulfite (0.4 g), and extracted with t-butyl methyl ether (30 ml) 4 times. The combined organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, concentrated under reduced pressure, and subjected to silica gel column chromatography (hexane: ethyl acetate=5:1 to hexane: ethyl acetate=1:1) to give 0.692 g of 4-(2,4,6-triethylphenyl)-2-methyl-5-methylsulfinyl-6-trifluoromethyl-2,3-dihydro-3-pyridazinone ((2-49)-(1)-40).
