标题化合物 C19H21N3O3S 是通过官能化亚氨基正膦与异氰酸苯酯在温和条件下进行氮杂维蒂希反应合成的。分子中，稠合的噻吩并嘧啶环系基本上是平面的，最大偏差为0.072 (2) Å，与苯环形成的二面角为60.11 (9)°。分子内存在C—H⋯O氢键。晶体堆积通过分子间 N—H⋯O 和 C—H⋯O 氢键稳定。
The title compound, C19H21N3O3S, was synthesized via the aza-Wittig reaction of functionalized iminophosphorane with phenyl isocyanate under mild conditions. In the molecule, the fused thienopyrimidine ring system is essentially planar, with a maximum deviation of 0.072 (2) Å, and makes a dihedral angle of 60.11 (9)° with the phenyl ring. An intramolecular C—H⋯O hydrogen bond is present. The crystal packing is stabilized by intermolecular N—H⋯O and C—H⋯O hydrogen bonds.
