In the title compound, C(16)H(17)ClN(4)O(2)S, the bicyclic triazolopyrimidine ring system is nearly planar and oriented with respect to the benzene ring at a dihedral angle of 87.24 (3)°. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers; an intra-molecular C-H⋯O hydrogen bond is also present. ...[more]
