title: 6-Chloro-N-methyl-N-phenyl-pyrimidine-4,5-diamine.
abstract: In the title compound, C(11)H(11)ClN(4), the dihedral angle between the aromatic rings is 66.47 (8)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating C(5) chains propagating in [010]. Slipped aromatic π-π stacking between centrosymmetrically related pairs of pyrim-idine rings also occurs [centroid-centroid separation = 3.7634 (12)Å and slippage = 1.715 Å].
