A new synthetic route of 105020-39-1

The synthetic route of 105020-39-1 has been constantly updated, and we look forward to future research findings.

105020-39-1, name is Methyl 2-Methyl-1,2,3-triazole-4-carboxylate, belongs to triazoles compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. COA of Formula: C5H7N3O2

Step 2:; 2-methyl 2H-1 ,2,3-triazole-4-carboxylic acid methyl ester (263 mg, 1.86 mmol) is charged in a round-bottom flask, then THF (15 mL), 1 M solution NaOH (9.3 mL, 9.3 mmol, 5.0 equiv) and MeOH (5 mL) are measured and mixed in a graduated cylinder, then added to the flask. The solution is stirred at RT. After 4 h, 1 M HCI is added (10 mL) and the solvent is evaporated. EtOAc is added and the layers are separated. The solvent is evaporated which affords the product R2j.1H NMR (400 MHz,DMSO-d6): delta 8.17 (s, 1 H), 4.22 (s, 3H).

The synthetic route of 105020-39-1 has been constantly updated, and we look forward to future research findings.
