2-[(4,6-Di-amino-pyrimidin-2-yl)sulfan-yl]-N-(2-methyl-phen-yl)acetamide

In the title compound, C13H15NOS, the plane of the pyrimidine ring makes a dihedral angle of 54.73 (9)° with that of the o-tolyl ring. The mol-ecule adopts an extended conformation, which is evident from the C-C(=O)-N-Car (ar = aromatic) torsion angle of 178.42 (15)°. In the crystal, mol-ecules are linked via pairs of N-H⋯N hydrogen bonds, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked by N-H⋯O and C-H⋯O hydrogen bonds, with the O atom accepting three such interactions, forming sheets parallel to (100).
