Reaction Steps

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) (52.2 mg), ethanol (674.3 mg), and sodium ethoxide (121.8 mg) were added under a nitrogen atmosphere at room temperature and stirred for 4 hours at 70° C. To the reaction mixture was added water (4 ml) at room temperature, and extracted with tert-butyl methyl ether. The organic layer was concentrated under reduced pressure to give 83.6 mg of 5-ethoxy-4-(2,6-diethyl-4-methylphenyl)-2,6-dimethyl-2,3-dihydro-3-pyridazinone ((1-6)-(1)-39).
