抄録

In the title compound, C₂₂H₁₉N₂OCl, the dihydropyridimine (DHPM) ring adopts a sofa conformation. The chlorophenyl moiety is oriented perpendicular with respect to the hetero ring. The molecules are joined by N-H…O intermolecular hydrogen bonds, forming centrosymmetric dimers. The crystal packing is stabilized by weak C-H…O, N-H…Cl and C-H…π (arene) interactions.
