Adding a certain compound to certain chemical reactions, such as: 956317-36-5, name is 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid, 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 956317-36-5, 956317-36-5
Example 5: Preparation of Compound 5 (S)-(5-methyl-2-(2H-1,2,3-triazol-2-yl)phenyl)(5-(((5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-6-azaspiro[2.5]octan-6-yl)methanone; [Show Image] 5-methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid (1eq; prepared according to WO 2008147518), HOBT (1 eq) and EDCl.HCl (1.5eq) dissolved in dichloromethane (5ml/mmol) were stirred at 25C for 0.5-2hours, then intermediate 2 (1 eq) dissolved in dichloromethane was added. After 18 hours the mixture was poured in an aqueous saturated solution of NaHCO3 and extracted with dichloromethane. The crude was purified by silica gel column chromatography (DCM to DCM/MeOH = 9/1) to obtain the title compound with yield of 52%. 1 HNMR (CDCl3) delta ppm 8.22-8.38 (m, 1 H), 7.94-8.14 (m, 1 H), 7.79-7.86 (m, 1 H), 7.69 (m, 1 H), 7.50-7.62 (m, 1 H), 7.28-7.37(m, 1 H), 7.0-7.24(m, 1 H), 6.48-6.66 (m, 1 H), 5.20(m, 1 H), 4.34-4.84 (m, 1 H), 3.89-4.0 (m, 1 H),3.65-3.75 (m, 1 H), 3.21-3.44 (m, 2H), 3.01-3.11 (m, 1 H), 2.26-2.46 (m, 3H), 1.89-2.17 (m, 1 H), 1.02-1.28 (m, 1 H), 0.19-0.63(m, 4H) MS= ESI + m/z 439 [M+H]+
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid, other downstream synthetic routes, hurry up and to see.
