Participants

Reaction Steps

To a solution of 4-(2,6-diethyl-4-methylphenyl)-6-hydroxymethyl-5-(4-methylphenylsulfonyl)-2-methyl-3(2H)-pyridazinone (2.40 g, 5.45 mmol) and diisopropylethylamine (10 ml, 57.4 mmol) in THF (20 ml) was added chloromethyl methyl ether (2.4 ml, 31.6 mmol), and refluxed for 4 hours. After the reaction solution was cooled to room temperature, to the reaction solution was added saturated aqueous sodium hydrogen carbonate solution, and extracted with ethyl acetate 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 2.11 g of 4-(2,6-diethyl-4-methylphenyl)-6-methoxymethoxymethyl-5-(4-methylphenylsulfonyl)-2-methyl-3(2H)-pyridazinone (yield: 80%) as solid.
