title: (2Z)-Ethyl 5-(4-methoxy-phen-yl)-7-methyl-3-oxo-2-(3,4,5-trimethoxy-benzyl-idene)-3,5-dihydro-2H-thia-zolo[3,2-a]pyrimidine-6-carboxyl-ate.
abstract: In the title compound, C(27)H(28)N(2)O(7)S, the dihedral angles between the thia-zole ring and the mono- and tris-ubstituted benzene rings are 87.8 (2) and 17.9 (3)°, respectively. The dihydro-pyrimidine ring adopts a flattened boat conformation. In the crystal structure, π-π stacking occurs [centroid-centroid separation = 3.6611 (11) Å].
