title: 2-(Dibutyl-amino)-3-(4-fluoro-phen-yl)-5,6,7,8-tetra-hydro-7-methyl-6,8-di-phenyl-pyridine-[3',4':2,3]thieno[5,4-d]pyrimidin-4(3H)-one.
abstract: In the crystal structure of the title compound, C(36)H(39)FN(4)OS, the two fused rings of the thienopyrimidine system are coplanar. The 4-fluoro-phenyl ring is twisted with respect to the heterocyclic pyrimidinone ring by 67.21 (14)°. The piperidine ring shows a half-chair conformation. One of the n-butyl chains is disordered equally over two sites. The crystal packing is stabilized by C-H⋯O hydrogen bonds.
