In the title compound, C15H19N3, the pyrimidine ring is approximately planar [maximum deviation = 0.007 (1) Å] and forms a dihedral angle of 3.15 (6)° with the benzene ring. In the crystal packing, intermolecular N-HN hydrogen bonds link pairs of neighbouring molecules into dimers with R22(8) ring motifs. These dimers are stacked along the b axis.
