Participants

Reaction Steps

In 10 ml of N,N-dimethylformamide were dissolved 1.4 g of 2-(2-chloro-2-methylpropyl)-4,5-dichloro-3(2H)-pyridazinone and 1.29 g of 2-iodo-5-pyridyl methanol, and thereto was added 0.33 g of powdery potassium hydroxide under ice-cooling. The mixture solution was stirred for one day at room temperature. Then, the procedures in Preparation Example 2 were repeated to give 0.74 g of 4-chloro-2-(2-chloro-2-methylpropyl)-5-[(2-iodo-5-pyridyl)methoxy]-3(2H)-pyridazinone (m.p.: 119°-123° C.) and 0.24 g of 4-chloro-5-[(2-iodo-5-pyridyl)-methoxy]-2-(2-methyl-1-propenyl)-3(2H)-pyridazinone (m.p.: 141°-142° C.).
