Adding some certain compound to certain chemical reactions, such as: 3641-08-5, name is 2H-1,2,4-Triazole-3-carboxamide, 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 3641-08-5. 3641-08-5
A stirred mixture of 1H-1,2,4-triazole-3-carboxamide (500 mg, 4.46 mmol) in 1,2-dichloroethane (4.46 mL) treated at room temperature with 2,6-lutidine (2.08 mL, 17.84 mmol) and triethylsilyl trifluoromethanesulfonate (3.03 mL, 13.38 mmol) and heated under a nitrogen atmosphere at 50C. After 4 hours of heating the reaction solution allowed to cool to room temperature and diluted with dichloromethane (25 mL), washed with water (25 mL), 0.5M hydrochloric acid (25 mL), water (25 mL), dried over MgSO4, filtered, and evaporated to solid. The solid was flash chromatographed (silica gel, 10-65% ethyl acetate:hexane) to give the product as a white solid (683 mg).1H NMR (CDCl3, 500MHz, ppm) 0.89 (q, J=8Hz, 6H, CH2), 1.03 (t, J=8 Hz, 9H, CH3), 6.77 (s, 1H, NH), 8.63 (s, 1H, triazole H-5).LC/MS m/z (positive ion scan) M+l= 227.20.
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 2H-1,2,4-Triazole-3-carboxamide.
