Adding some certain compound to certain chemical reactions, such as: 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 7170-01-6. 7170-01-6
A mixture of compound 5z (220 mg, 0.5 mmol), 3-methyl-1,2,4-triazole (830 mg, 10 mmol; 20 eq.; prepared by the method described in Coll. Czech. Chem. Comm. 1985, 49, 2492), copper powder (63.5 mg, 1 mmol; 2 eq.), potassium carbonate (138 mg, 1 mmol; 2 eq.) was flushed with anhydrous nitrogen and heated in a sealed tube at 160 C. for 11 h. Upon cooling, to the mixture was added MeOH, and the insoluble material was filtered. The filtrate was concentrated in vacuo and purified by C-18 reverse phase column (Prep. System eluting with gradient 0-70% MeOH-water containing 0.1% TFA) to obtain 24 mg (0.049 mmol, Y. 9.8%) of the title compound Example 317 as amorphous powder (TFA salt): MS m/e 488 (MH); 1H NMR (CD3OD) delta ppm 1.30, 1.35 (3H, 2d, J=7 Hz), 2.54 (3H, s, CH3), 3-4.5 (8H, m, CH2N), 4.04, 4.05 (3H, 2s, CH3O), 7.46, 7.47 (5H, 2s, Ar-Hs), 7.85, 7.86 (1H, 2s), 8.28, 8.31 (1H, 2s), 9.22 (1H, s).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 3-Methyl-1H-1,2,4-triazole.
