29-Sep-2021 News New downstream synthetic route of 6086-21-1

I am very proud of our efforts over the past few months and hope to 1-Methyl-1,2,4-triazole help many people in the next few years.

Synthetic Route of 6086-21-1, New Advances in Chemical Research in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 6086-21-1, name is 1-Methyl-1,2,4-triazole, molecular formula is C3H5N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.

Example 133.; Preparation of 8-(1-ethyl-propyl)-3-[3-methoxy-5-(2-methyl-2H-[1,2,4]triazol-3-yl)- thiophen-2-yl]-2,6-dimethyl-imidazo[1,2-b]pyridazine.; A. 5-Bromo-1-methyl-1H-[1,2,4]triazole.; EPO To a -78 °C solution of l-methyl-1H-[1,2,4]triazole (1.0 mL, 13.20 mmol) and TEtaF (100 mL) is added 1.6 M n-BuLi (8.70 mL, 13.86 mmol). After 45 minutes 1,2- dibromo-l,1,2,2-tetrafluoro-ethane (1.76 mL, 14.52 mmol) is added, the solution is warmed to ambient temperature and stirred for 2 hours. The solution is diluted with EtOAc (200 mL), washed with water (150 mL), brine (150 mL), dried over MgSO4, filtered and concentrated to furnish the title compound (1.37 g, 8.46 mmol, 64percent). 1H NMR (CDCl3) delta 3.82 (s, 3H), 7.78 (s, 1H). LC/MS (m/z): calcd. for C3H4BrN3 (M+H)+: 162.0; found: 161.9.

I am very proud of our efforts over the past few months and hope to 1-Methyl-1,2,4-triazole help many people in the next few years.
