title: Ethyl 7-methyl-2-((1-methyl-1H-pyrrol-2-yl)methyl-ene)-3-oxo-5-phenyl-3,5-dihydro-2H-thia-zolo[3,2-a]pyrimidine-6-carboxyl-ate.
abstract: In the structure of the title compound, C(22)H(21)N(3)O(3)S, the thia-zole ring forms dihedral angles of 88.83 (7) and 9.39 (9)°, respectively, with the benzene and pyrrole rings. The dihydro-pyrimidine ring adopts a flattened boat conformation. The olefinic double bond is in a Z conformation.
