Abstract
The title compound, C22H21ClFNO6, was synthesized by the 1,3-dipolar cycloaddition reaction of dimethyl maleate, methyl 2-amino-2-phenylacetate and 2-chloro-4-fluorobenzaldehyde. The pyrrolidine ring possesses an envelope conformation and the two benzene rings are oriented at a dihedral angle of 68.28 (7)°. Weak intermolecular C—H⋯O hydrogen bonding is present in the crystal structure. One methyl group is disordered over two positions with a site-occupancy ratio of 0.651 (12):0.349 (12).
