2-[(4,6-Di­amino­pyrimidin-2-yl)sulfan­yl]-N-(2-methyl­phen­yl)acetamide

In the title compound, C(13)H(15)NOS, the plane of the pyrimidine ring makes a dihedral angle of 54.73 (9)° with that of the o-tolyl ring. The mol­ecule adopts an extended conformation, which is evident from the C—C(=O)—N—C(ar) (ar = aromatic) torsion angle of 178.42 (15)°. In the crystal, mol­ecules 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).
