Abstract: In the molecule of the title compound, C38H37N3O7, the pyrrolidine ring adopts a twist conformation and the six-membered heterocyclic ring has a boat conformation. In the crystal structure, molecules are linked into a three-dimensional framework through intermolecular C-HO hydrogen bonds. One ethyl group is disordered over two positions with occupancies 0.67 (2)/0.33 (2).
