摘要
The title compound, C26H23F2NO3, was synthesized by the reaction of 2-(4-fluorobenzylidene)-4-methyl-3-oxo-N-phenylpentanamide and 4-fluorobenzaldehyde. The dihedral angles between the mean plane through the pyrrolidine ring (nearly planar; maximum deviation of 0.145 A for the C atom bearing the hydroxy group) with the phenyl and benzene rings are 37.22 (7), 51.88 (7) and 87.64 (9)degrees, respectively. The pyyolidine ring is near coplaner, with max offset of 0.145 A for C19 atom.\uff09 In the crystal, molecules are linked by pairs of O-H...O hydrogen bonds into inversion dimers, which are further assembled into chains parallel to the b axis by weak C-H...O hydrogen bonds.
