Electric Literature of 4928-87-4, New Advances in Chemical Research in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 4928-87-4, name is 1,2,4-Triazole-3-carboxylic acid, molecular formula is C3H3N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
Example 2. Synthesis of N-{4-[(pyrimidin-2-yl)sulfamoyl]phenyl}-lH-l,2,4- triazole-3-carboxamide, 1-18 1-18 [00267] Compound 1-18 was prepared according to the reaction sequence in Scheme IV with several adaptations. The solvent was removed in vacuo, the remaining material was triturated from H2O/CH3CN 1 : 1 (20ml), washed with small volumes of DMSO/CH3CN 1 :2, collected and dried to afford 190mg (65%) of N-{4-[(pyrimidin-2-yl)sulfamoyl]phenyl}-lH-l,2,4-triazole-3- carboxamide 1-18 as a colourless solid. 1H NMR (500 MHz, DMSO-d6) delta 14.84 (s, 1H), 11.70 (s, 1H), 10.83 (s, 1H), 8.66 (s, 1H), 8.50 (d, J = 4.9 Hz, 2H), 8.02 (d, J = 8.9 Hz, 2H), 7.95 (d, J = 8.9 Hz, 2H), 7.04 (t, J = 4.9 Hz, 1H).
