✦ Synopsis

In the title compound, C 27 H 23 N 3 O 3 , the central pyrrolidine ring adopts an envelope conformation. In the crystal structure, the molecules exist as centrosymmetric N-HÁ Á ÁO hydrogenbonded dimers. The dimers are linked via C-HÁ Á ÁO and C-HÁ Á Á hydrogen bonds, forming a chain along the b axis.
