In the title compound, C11H13N3O, the phenyl ring is disordered over two sites, with occupancy factors in a 0.520 (17):0.480 (17) ratio. The dihedral angle between the ring planes of the major and minor components of the disordered ring is 12.9 (2)degrees. In the crystal, molecules are linked by N-H center dot center dot center dot O hydrogen bonds, forming R-2(2) (8) ring motifs. C-H center dot center dot center dot O, C-H center dot center dot center dot N and C-H center dot center dot center dot pi interactions also occur.
