84956-71-8, 2-(tert-Butyl)-4,5-dichloropyridazin-3(2H)-one is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
84956-71-8, Example 3 Synthesis of 2-tert-butyl-4-chloro-5-[2-(2-methyl-4-n-pentylphenoxy)ethylthio]-3(2H)-pyridazinone (Compound No. 12) In 20 ml of methanol were dissolved 1.8 g of 2-tert-butyl-4,5-dichloro-3(2H)-pyridazinone and 1.9 g of 2-(2-methyl-4-n-pentylphenoxy)ethylmercaptan, and then to the mixture was added dropwise a solution of 0.5 g of sodium methoxide dissolved in 5 ml of methanol. After dropwise addition, the mixture was stirred at room temperature for 1 hour to complete the reaction. Then, methanol was distilled off under reduced pressure, and an oily product which was separated by adding water was extracted with ethyl acetate The extract was washed with water, dried over anhydrous sodium sulfate, and then ethyl acetate was distilled off under reduced pressure. The oily product obtained was isolated by column chromatography (Wako Gel C-200, eluted with toluene: ethyl acetate = 9: 1) to give 2.8 g of the title compound as colorless oily liquid.
The synthetic route of 84956-71-8 has been constantly updated, and we look forward to future research findings.
