In the title compound, C13H12N4O2, all the non-H atoms lie on a crystallographic mirror plane and an intramolecular N—H...N hydrogen bond generates an S(5) ring; the conformation about the imine bond [1.280 (3) Å] is E. In the crystal, molecules assemble into a two-dimensional array via C—H...O(carbonyl) and C—H...N(pyrazine) contacts. Layers stack along the b-axis direction via weak π–π interactions between pyrazine rings [ring centroid distance = 3.8028 (8) Å].
