Özet

In the title compound, C21H19N3O3S, the 5,6,7,8-tetrahydropyridine ring adopts a half -chair conformation. The fusedthieno[2,3-d]pyrimidine ring system is essentially planar (r.m.s. deviation = 0.001 angstrom) and forms a dihedral angle of 2.66 (6)degrees with the attached phenyl ring. The three-dimensional crystal packing is stabilized by C-H center dot center dot center dot O and C-H center dot center dot center dot N hydrogen bonds and C-H center dot center dot center dot pi interactions.
