RESUMO
In the racemic title compound, C(22)H(23)NO(7), the dihedral angle between the fused ring systems is 51.87â (6)°. Two of the meth-oxy groups are disordered over two orientations in 0.688â (5):0.312â (5) and 0.672â (15):0.328â (15) ratios. In the crystal, weak C-Hâ¯O inter-actions link the mol-ecules.
