Reaction Steps

To a 30 ml volume three-necked flask, 4-(2,6-diethyl-4-methylphenyl)-2-methyl-5-methylsulfinyl-6-trifluoromethyl-2,3-dihydro-3-pyridazinone ((2-49)-(1)-39) (0.375 g), N-methylpyrrolidone (3.49 g), water (1.75 g), and sodium hydroxide (0.34 g) were added at room temperature. The resulting mixture was stirred at 50° C. for 4 hours. Then, the resulting mixture was cooled to room temperature, added 12N hydrochloric acid (1.5 ml) and water (15 ml), and extracted with ethyl acetate (30 ml). The organic layer was dried over anhydrous magnesium sulfate, concentrated under reduced pressure, and subjected to silica gel column chromatography (hexane:ethyl acetate=7:1 to hexane:ethyl acetate=5:1 to hexane:ethyl acetate=3:1) to give 0.147 g of 4-(2,6-diethyl-4-methylphenyl)-5-hydroxy-2-methyl-6-trifluoromethyl-2,3-dihydro-3-pyridazinone ((1-16)-(1)-39).
