Adding a certain compound to certain chemical reactions, such as: 67545-00-0, name is 4-Amino-1-methyl-1,2,3-triazole, 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 67545-00-0, name: 4-Amino-1-methyl-1,2,3-triazole
In a microwave vial (35 mL) was added S-129 (0.78 g, 1.82 mmol), amine 11 (0.18 g, 1.82 mmol), Cs2CO3(1.18 g, 3.64 mmol.) and Dioxane (25 mL). The Argon was purged through septum and the reaction mixture was degassed for about 5 min. To this mixture was added Xantphos (103 mg, 0.2 mmol) followed by Pd2(dba)3(162 mg, 0.2 mmol) and purged with Argon again for 5 min. Vial was sealed with the septum and irradiated at 140 C for 3 h. After filtration, the obtained crude was chromatographed (Biotage, 25 g, eluent: DMC-EtOAc: 10-50%) to afford S-6-1 (390 mg, 44%).1H NMR (400 MHz, DMSO-d6): delta 9.61 (bs, 1H), 7.99 (d, J = 7.8 Hz, 1H), 7.46- 7.10 (m, 10H), 6.87 (d, J = 3.9 Hz, 1H), 5.39 (m, 1H), 4.02 (s, 3H), 3.35- 3.23 (m, 2H), 2.32 (s, 3H), 2.23 (m, 2H). FABMS (M+H) calculated for was 489.1815 found 489.1813. LCMS 99%, tR= 7.37 minutes.
