반응 단계

In 30 mm of N,N-dimethylformamide was dissolved 2.2 g of 2-t-butyl-4-chloro-5-mercapto-3(2H)-pyridazinone and 2.3 g of 2-(2',6'-dimethylphenoxy)ethyl bromide, and thereto were added 1.1 g of anhydrous sodium carbonate. The resulting solution was stirred at room temperature for fifteen hours. This solution was poured into water and extracted with diethyl ether. The organic layer was dried over anhydrous sodium sulfate and freed of solvent under reduced pressure to give crystals. The crystals thus obtained were washed with n-hexane to give 3.5 g of the intended compound. m.p. 104.3°~105.2° C.
