description The title compound, C(26)H(33)NO(7), comprises a racemic mixture of asymmetric mol­ecules containing one stereogenic centre. The dihedral angle between the mean planes of the fused pyran ring and the coumarin ring system is 8.12 (14)°. The mol­ecular structure features a short N—H⋯O contact, which generates an S(6) ring motif. The crystal packing are stabilized by C—H⋯O inter­actions.
