title: 9-{[4-(Dimethyl-amino)-benz-yl]amino}-5-(3,4,5-trimeth-oxy-phen-yl)-5,5a,8a,9-tetra-hydro-furo[3',4':6,7]naphtho-[2,3-d][1,3]dioxol-6(8H)-one.
abstract: In the title compound, C(31)H(34)N(2)O(7), the fused tetra-hydro-furan and six-membered rings each display an envelope conformation. The dihedral angles between the benzene ring of the benzo[d][1,3]dioxole and the other two benzene rings are 89.68 (3) and 63.38 (2)°. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules.
