Reaction Steps
To a solution of 4-(2,6-diethyl-4-methylphenyl)-6-methoxymethoxymethyl-5-(4-methylphenylsulfonyl)-2-methyl-3(2H)-pyridazinone (2.38 g, 4.91 mmol) and benzylalcohol (797 mg, 7.37 mmol) in dry DMF (10 ml) was added 60% sodium hydride (294 mg, 7.35 mmol) at 5° C. The reaction solution was stirred at 0° C. for 1 hour. The reaction solution was diluted with water, and extracted with tert-butyl methyl ether 2 times. The combined organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=2:1) to give 2.12 g of 4-(2,6-diethyl-4-methylphenyl)-6-methoxymethoxymethyl-5-benzyloxy-2-methyl-3(2H)-pyridazinone (yield: 99%) as oil.
