Abstract

In the racemic title compound, C22H23NO7, the dihedral angle between the fused ring systems is 51.87 (6)°. Two of the meth-oxy groups are disordered over two orientations in 0.688 (5):0.312 (5) and 0.672 (15):0.328 (15) ratios. In the crystal, weak C - H⋯O inter-actions link the mol-ecules.
