Procedure

In a 25 mL sealed tube, methyl 2-(pyrazin-2-yl)acetate (0.25 g, 1.0 eq.) was dissolved in ethanol (5 mL) at RT. Hydrazine hydrate (0.33 g, 4 eq.) was introduced dropwise at RT and the reaction mixture was heated at 120° C. for 20 h. The reaction mixture was concentrated under reduced pressure (40° C., 20 mm Hg) to afford the crude 2-(pyrazin-2-yl)acetohydrazide (0.2 g) which was used without further purification in the following step.
