In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6818-99-1, name is 3-Chloro-1,2,4-triazole belongs to Triazoles compound, it is a common compound, a new synthetic route is introduced below. 6818-99-1
2- [6-Chloro-3- (ethanesulfonyl) pyridin-2-yl] -3-methyl-6-[(trifluoromethyl) sulfanyl]-3H-imidazo [4,5-b] pyridine 200 mg, 60% sodium hydride (oily) 37 mg, and a mixture of 2 mL of DMF, was added under ice-cooling 3-chloro-1H-1,2,4-triazole 67 mg. After the mixture was stirred under ice-cooling for 2.5 hours, a saturated aqueous solution layer was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, and saturated brine, and dried with anhydrous sodium sulfate. The resulting organic layer was dried under reduced pressure. The resulting residue was subjected to silica gel chromatography to obtain 171mg of the compound of the present invention beta38 referred to below.
The synthetic route of 6818-99-1 has been constantly updated, and we look forward to future research findings.
