1H-1,2,4-Triazole-1-carboximidamide hydrochloride Usage And Synthesis

Chemical Properties

White crystalline

Uses

[1,2,4]Triazole-1-carboxamidine is an intermediate used in the synthesis of peramivir (P285500), a neuraminidase inhibitor developed as an antiviral agent for the treatment of influenza.

Synthesis

1H-1,2,4-Triazole-1-carboxamidine hydrochloride is prepared by the reaction of dicyandiamide and 1,2,4-Triazole. The steps are as follows:
Dissolve the compound (19.7 g, 0.29 mol) in 20 ml of tetrahydrofuran, and the temperature was raised to 70℃. A solution of dicyandiamide (20 g, 0.24 mol) was added and a solution of 4 mol / L HCl in tetrahydrofuran 27 g, 0.26 mol) at 70℃ for 2 h, the temperature was removed and cooled to room temperature. The solid was removed by filtration and 26.0 g was removed by filtration. The solvent was dried in vacuo at 45℃ to give a colorless oil which was recrystallized from methanol: dichloromethane = 2: 1 Of the mixed solution 50ml recrystallization, cooling crystallization, suction filter to get 6.2g solid, drying a total of 30.1g white powder. Yield 90.3%, purity 99,8%.
