The title compound, C 18 H 18 ClN 7 OS, the mean plane of the triazolopyrimidine system makes dihedral angles of 77.54 (13) and 80.15 (13) , respectively, with the attached phenyl and 2chlorothiazole rings. The crystal packing is stabilized by intermolecular N-HÁ Á ÁN hydrogen bonds and weakstacking
