ABSTRACT
The title compound, C(22)H(18)ClN(3)S, was synthesized by the reaction of 4-chloro-benzaldehyde, tetra-hydro-thio-pyran-4-one and 3-methyl-1-phenyl-1H-pyrazol-5-amine in acetic acid without a catalyst. The pyridine and pyrazole rings are almost coplanar, the dihedral angle between their mean planes being 2.50â
(1)°. The thio-pyran ring exhibits an envelope conformation. The crystal packing is stabilized by inter-molecular C-Hâ¯Cl hydrogen bonds and by C-Hâ¯π and π-π inter-actions [centroid-centroid distances of 3.825â
(2)â
Å between pyridine rings and 3.557â
(2)â
Å between pyrazole and pyridine rings.
