Participants

Reaction Steps

In 20 ml of N,N-dimethylformamide were dissolved 1.7 g of 2-t-butyl-4-chloro-5-mercapto-3(2H)-pyridazinone and 2.8 g of 4-(2-hexyloxy-1-methylethoxy)-benzyl bromide, and the resulting solution was stirred overnight at room temperature. The crude product which had been obtained similarly to the procedures in Preparation Example 3 was isolated through column chromatography [eluting with benzene/ethyl acetate (18/1)] to give 3.4 g of the aimed product as an oil.
