Adding a certain compound to certain chemical reactions, such as: 6523-49-5, name is 4-(1,2,4-Triazol-1-yl)aniline, belongs to Triazoles compound, 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 6523-49-5, HPLC of Formula: C8H8N4
A cooled (0 0C) solution of 6-(cyclopropylmethyl(propyl)amino)pyrimidine-4- carboxylic acid (Intermediate 21 , 112 mg; 0.45 mmol) in DCM was treated with diisopropylethylamine (78.4 ml 0.52 mmol) and methyl chloroformate (36.2 ml 0.47 mmol). After stirring at 0 0C for 15 minutes, 4-(1 H-1 ,2,4- triazol-1-yl)aniline (Maybridge, 108 mg; 0.67 mmol) was added and the mixture stirred for 72 hours. The solvent was evaporated and the compound purified by preparative HPLC to give the title compound as a white solid.1H NMR (400MHz, CDCI3) delta 10.13 (1 H, s), 8.56 (2H, d, J = 13.9 Hz), 8.11 (1 H, s), 7.93 (2H, d, J = 8.6 Hz), 7.70 (2H, d, J = 8.6 Hz), 7.36 (1 H, s), 3.53 (4H, s), 1.75-1.65 (2H, m), 1.10 (1 H, s), 0.97 (3H, t, J = 7.4 Hz), 0.58 (2H, d, J = 7.7 Hz), 0.35-0.30 (2H, m). MS (ESI+) 378. HPLC (Condition C) Rt 3.70 min (HPLC purity 99.8%).
