Synthetic Route of 7170-01-6, New Advances in Chemical Research in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole, molecular formula is C3H5N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
EXAMPLE 102 [2-Chloro-4-(3-methyl-1,2,4-triazol-1-yl)-phenyl](5H,11H-pyrrolo[2,1-c]-[1,4]benzodiazepin-10-yl)-methanone To a suspension of 60% sodium hydride in oil (0.3 g) in dimethylformamide (50 ml) was added dropwise 3-methyl-1,2,4-triazole (0.45 g). After hydrogen gas evolution ceased, 2-chloro-4-fluorophenyl-(5H,11H-pyrrolo[2,1-c][1,4]benzodiazepine-10-yl)-methanone (1.70 g) was added and the reaction mixture was heated in a sand bath at 110 C. for 18 hours. The mixture was poured onto ice, diluted with brine, and extracted with dichloromethane. The combined extracts were dried over anhydrous sodium sulfate and filtered through a short column of anhydrous sodium magnesium silicate. The solution was concentrated in vacuo and the residue was triturated with diethyl ether to give 1.25 g of the title compound as colorless crystals, m.p. 191-193 C., MS m/z: 404.1 (M+H)+.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 3-Methyl-1H-1,2,4-triazole is helpful to your research.
