Abstract: The title compound, C21H17Cl1N2O2, was synthesized by the reaction of 7-methoxy-2-tetralone, 2-chlorobenzaldehyde and malononitrile in the presence of triethylbenzylammonium chloride in an aqueous medium. X-ray analysis reveals that the pyran ring and the fused six-membered ring adopt boat and half-chair conformations, respectively.
