3-Amino-1-(2-chloro­phenyl)-9-meth­oxy-5,6-dihydro-1H-benzo[f]chromene-2-carbonitrile

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.
