Ethyl 2-(2-acetoxy-benzyl-idene)-7-methyl-3-oxo-5-phenyl-2,3-dihydro-5H-1,3-thia-zolo[3,2-a]pyrimidine-6-carboxyl-ate.

ABSTRACT: In the title mol-ecule, C(25)H(22)N(2)O(5)S, the atoms of the thia-zolopyrimidine ring system, with the exception of the phenyl-bearing C atom [deviation = 0.177 (2) Å], are essentially planar [r.m.s deviation = 0.100 (2) °] and the mean plane of these atoms forms dihedral angles of 89.86 (10) and 7.97 (8)° with the phenyl and benzene rings, respectively. In the crystal, co-operative C-H⋯O and C-H⋯π inter-actions lead to a supra-molecular chain along the a axis. These chains are connected via π-π inter-actions [centroid-centroid = 3.7523 (13) Å].
