Procedure
To a solution of 3-(trifluoromethyl)[1,2,4]triazolo[4,3-a]pyrazine (1.60 g) in methanol (20 mL) was added a catalytic amount of Pd/C. The suspension was stirred under H2 for 5 h, and then filtered. The filtrate was concentrated in vacuo to give a residue, which was used for next step without further purification.
