Synthetic Route of 274-82-8,Some common heterocyclic compound, 274-82-8, name is [1,2,4]Triazolo[4,3-a]pyrazine, molecular formula is C5H4N4, 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.

To a solution of [l ,2,4]triazolo[4,3-a]pyrazine (1.50 g) in MeOH ( 150 mL) was added Pt02 ( 1.10 g) and 10% Pd/C (0.46 g) at rt. The suspension was stirred under H2 at room temperature for 16 h and filtered. The filtrate was concentrated in vacuo andthe residue was chromatographed with a silica gel column to give the title compound (0.18 g, 1 1.54 %). The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 125.1 (M+l ).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route [1,2,4]Triazolo[4,3-a]pyrazine, its application will become more common.
