Procedure

To a test tube (outside diameter: 21 mm Φ×overall length: 160 mm), 4-(2,6-diethyl-4-methylphenyl)-2,6-dimethyl-5-methylsulfonyl-2,3-dihydropyridazin-3-one ((2-34)-(1)-39) (0.21 g), 1-butanol1 (4 ml, water (0.1 ml), and sodium hydroxide (0.20 g) were added under a nitrogen atmosphere at room temperature, and stirred at 120° C. for 8 hours. Then, to the reaction mixture was added water at room temperature, and extracted with tert-butyl methyl ether. The resulting organic layer was concentrated under reduced pressure to give 0.74 g of 5-(n-butoxy)-4-(2,6-diethyl-4-methylphenyl)-2,6-dimethyl-2,3-dihydro-3-pyridazinone ((1-5)-(1)-39).
