Versuchsvorschrift

To a 20 ml volume two-necked flask, 4-(2,6-diethyl-4-methylphenyl)-2,6-dimethyl-5-methylsulfanyl-2,3-dihydro-3-pyridazinone ((2-4)-(1)-39) (0.18 g), chloroform (1.0 ml), and sodium hydrogen carbonate (0.20 g) were added thereto under a nitrogen atmosphere. Meta-chloroperbenzoic acid (0.32 g) was added thereto at room temperature, and then the mixture was stirred for 4 hours. After stirring, to the reaction mixture was added saturated aqueous sodium sulfite solution, and extracted with tert-butyl methyl ether. Then, the organic layer was concentrated under reduced pressure. Then, the residue was subjected to column chromatography (silica gel 10 g, chloroform:ethyl acetate=15:1) to give 0.12 g of 4-(2,6-diethyl-4-methylphenyl)-2,6-dimethyl-5-methylsulfonyl-2,3-dihydro-3-pyridazinone ((2-34)-(1)-39).
