2-Tert-butyl-4,5-dichloro-2,3-dihydropyridazin-3-one → 2-t-butyl-4-chloro-5-[4-(2-diethylaminoethoxy)-alpha-methylbenzyloxy]-3(2H)-pyridazinone

Participants

Reaction Steps

By using 1.0 g of 2-t-butyl-4,5-dichloro-3(2H)-pyridazinone and 1.1 g of 4-(2-diethylaminoethoxy)-α-methylbenzyl alcohol and similarly to the procedures in Preparation Example 1, a crude product was obtained. The crude product was then purified through column chromatography (eluting with chloroform/methanol=200/5) to obtain 710 mg of the aimed product as an oil.
