3-(4-Fluorophenyl)-2-(4-methylphenoxy)-5,8,9-trimethylthieno[3',2':5,6]pyrido[4,3-d]pyrimidin-4(3H)-one

Abstract: In the title molecule, C25H20FN3O2S, the central tricyclic system is essentially planar. All bond lengths and angles are within normal ranges. The crystal packing is stabilized by [pi]-[pi] stacking interactions and van der Waals forces.
