Participants

Reaction Steps

To a test tube (outside diameter: 21 mm Φ×overall length: 160 mm), phenol (108 mg), toluene (930 mg), and 60% of oily sodium hydride (44 mg) were added, and stirred at room temperature for 5 minutes. To the mixture, (4-(2,6-diethyl-4-methylphenyl)-2,6-dimethyl-5-methylsulfonyl-2,3-dihydropyridazin-3-one ((2-34)-(1)-39) (299 mg) was added, and stirred at room temperature for 1.5 hours and at 100° C. for 1.5 hours. To the mixture, benzyltriethylammonium chloride was added and stirred for 1.5 hours, and then DMSO (1.1 ml) was added and stirred for 2 hours. After the mixture was cooled to room temperature, water was added and extracted with toluene 3 times. The organic layers were combined, washed with 2N aqueous sodium hydroxide solution 3 times, and concentrated under reduced pressure. The residue was subjected to column chromatography (hexane: ethyl acetate=3:1) to give 91 mg of 4-(2,6-diethyl-4-methylphenyl)-2,6-dimethyl-5-phenoxy-2,3-dihydro-3-pyridazinone ((1-31)-(1)-39).
