چکیده
In the title mol-ecule, C(21)H(16)Cl(2)O(2)S, the five-membered ring is rotationally disordered between two orientations in a 1:1 ratio. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules related by translation along the a axis into chains, which are further combined into layers parallel to the bc plane via C-H⋯π inter-actions. The crystal studied was a racemic twin with a 0.37 (19):0.63 (19) domain ratio.

In the title mol-ecule, C24H20Cl2O2, the central methyl-benzene ring forms dihedral angles of 42.47 (10) and 34.34 (10)° with the terminal 4-chloro-phenyl fragments. The dihedral angle between the chloro-benzene rings is 34.45 (11)°. A weak intra-molecular C-H⋯O inter-action generates an S(6) ring motif. The crystal packing exhibits weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions.

The cyclization of b-anilino propionic acids in the presence of polyphosphoric acid (PPA) afforded the 2,3-Dihydroquinoline-4-(1H)-ones in good yields. N,N'-bis(2-carboxyethyl)-4-methyl-1,2-diaminobenzene (7) is cyclized under this condition to produce the 1,5-diaza-2,3,6,7-tetrahydro-4-methyl-pheranthrene-4,8-dione(bis-quinolone) (8).
