실험 절차

In 30 ml of N,N-dimethylformamide were dissolved 2.0 g of 2-t-butyl-4-chloro-5-hydroxy-3(2H)-pyridazinone and 3.0 g of 4-(2-propoxyethoxy)-benzyl bromide, and then 2.0 g of anhydrous potassium carbonate was added thereto. The mixture was heated under stirring on an oil bath at 80° to 90° C. for 3 hours. Then, procedures similar to those in Preparation Example 2 were carried out to obtain 1.4 g of the aimed product as an oil.
