In the structure of the title compound, C26H18Cl3N3O2S—CH2Cl2, the C—S bond lengths in the thiophene ring [1.733 (5) and 1.735 (5) Å] are equivalent and long compared with the values observed in both free thiophene, measured using electron diffraction, and thieno[2,3-c]pyridine. The central thienopyridine ring system is planar. The pyrimidinone ring forms a dihedral angle of 3.1 (2)° with the pyridine ring. The chloro- and dichlorophenyl rings form dihedral angles of 75.2 (2) and 85.5 (2)°, respectively, with the pyrimidinone ring. The dihedral angle between the chlorophenyl rings is 69.7 (2)°. The cyclohexene ring adopts a half-chair conformation. There is a C—H—O hydrogen bond between the main molecule and the dichoromethane molecule. The dichloromethane molecule is disordered over two positions, with refined occupancies of 0.775 (6) and 0.225 (6). [ABSTRACT FROM AUTHOR]

The asymmetric unit of the title compound, C23H23ClN4OS, contains two crystallographically independent mol­ecules in which the orientations of the propyl­amine group and chloro­phenyl rings with respect to the fused ring system are different. The terminal cyclo­hexene ring adopts a half-chair conformation. The crystal packing is stabilized by N—H⋯O, N—H⋯N and C—H⋯O hydrogen bonds and π–π inter­actions. [ABSTRACT FROM AUTHOR]
