実験手順
To a solution of [1,2,4]triazolo[4,3-a]pyrazine (1.50 g) in MeOH (150 mL) was added PtO2 (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 and the residue was chromatographed with a silica gel column to give the title compound (0.18 g, 11.54%). The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 125.1 (M+1).
