Participants

Reaction Steps

To a 50 ml volume three-necked flask, 4-(2,6-diethyl-4-methylphenyl)-2-methyl-5-methylsulfanyl-6-trifluoromethyl-2,3-dihydro-3-pyridazinone ((2-46)-(1)-39) (0.51 g) and chloroform (12.5 ml) were added at room temperature. Sodium hydrogen carbonate (0.46 g) and meta-chlorobenzoic acid (0.48 g) was added and the resulting mixture was stirred at room temperature for 3 hours. Then, the reaction mixture was poured into water (20 ml), added sodium sulfite (0.3 g), and extracted with t-butyl methyl ether (40 ml) 2 times. Then, the 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=3:1 to hexane:ethyl acetate=1:1) to give 0.461 g of 4-(2,6-diethyl-4-methylphenyl)-2-methyl-5-methylsulfinyl-6-trifluoromethyl-2,3-dihydro-3-pyridazinone ((2-49)-(1)-39).
