RESUMO
The title compound, C(19)H(21)N(3)O(3)S, was synthesized via the aza-Wittig reaction of functionalized imino-phospho-rane with phenyl isocyanate under mild conditions. In the mol-ecule, the fused thienopyrimidine ring system is essentially planar, with a maximum deviation of 0.072â (2)â Å, and makes a dihedral angle of 60.11â (9)° with the phenyl ring. An intra-molecular C-Hâ¯O hydrogen bond is present. The crystal packing is stabilized by inter-molecular N-Hâ¯O and C-Hâ¯O hydrogen bonds.
