5-(4-Chloro-phen-yl)-1-methyl-3-phenyl-3,6,8,9-tetra-hydro-pyrazolo-[3,4-b]thio-pyrano[4,3-d]pyridine.


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 2.50?(1)°. The thio-pyran ring exhibits an envelope conformation. The crystal packing is stabilized by inter-molecular C-H?Cl hydrogen bonds and by C-H?? and ?-? inter-actions [centroid-centroid distances of 3.825?(2)?Å between pyridine rings and 3.557?(2)?Å between pyrazole and pyridine rings.
