Ethyl 5-chloro-methyl-2-methyl-sulfanyl-7-phenyl-4,7-dihydro-1,2,4-triazolo[1,5-a]pyrimidine-6-carboxyl-ate. 2007

Dan-Dan Song, and Qiong Chen

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.
