Reaction Steps

In 15 ml of N,N-dimethylformamide were dissolved 1.0 g of 2-t-butyl-4-chloro-5-hydroxy-3(2H)-pyridazinone and 1.6 g of 4-(1-methyl-2-isopropoxyethoxy)-benzyl bromide, and thereto was added 1.0 g of anhydrous potassium carbonate. The mixture was heated under stirring on an oil bath at 100° to 120° C. for 2 hours. Then, procedures similar to those in Preparation Example 2 were conducted to give 1.2 g of the aimed compound, m.p. 60.0°~62.0° C.
