7170-01-6, These common heterocyclic compound, 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
4-chloro-8-methoxy-2- methylquinoline (100 mg, 0.481 mmol) was reacted with 3-methyl- IH-l, 2,¡¤ 4-triazole (46.0, 0.554 mmol) according to the synthesis of 4-(4-fluoro- 1 /Y-pyrazol- 1 -yl)-8-mcthoxy-2-mcthylquinolinc to give a mixture of the title compounds. MS (m/z): 255.3 [M+H+] Step B Synthesis of 2-methyl-4-(3-methyl-l//-l,2,4-triazol-l-yl)quinolin-8-ol and 2-methyl- 4-(5-methyl- 1 H- 1 ,2,4-triazol- 1 -yl)quinolin-8-ol (0284) A mixture of 8-mcthoxy-2-mcthyl-4-(5-mcthyl- 1 H- 1 ,2,4-triazol- 1 -yl)quinolinc and 8- mcthoxy-2-mcthyl-4-(3-mcthyl- 1 H- 1 ,2,4-triazol- 1 -yl)quinolinc (153 mg, 0.602 mmol) was demethylated according to the synthesis of 4-(4-fluoro-l//-pyrazol-l-yl)-2-methylquinolin-8-ol to give a mixture of the title compounds. MS (m/z): 241.1 [M+H+]
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 7170-01-6.
