N-tert-But­oxy­carbonyl-α-(2-fluoro­benzyl)-l-proline

In the title compound, C(17)H(22)FNO(4), the pyrrolidine ring adopts an envelope conformation with the disordered com­ponents of the methylene C atom, with site occupancies of 0.896 (7) and 0.104 (7), being the flap on either side of the mean plane involving the other atoms of the ring. The carb­oxy­lic acid group forms dihedral angles of 72.06 (11) and 45.44 (5)° with the N-tert-but­oxy­carbonyl group and the 2-fluoro­benzyl group, respectively. In the crystal, two-dimensional layers of mol­ecules parallel to (001) are built through an R (4) (4)(23) motif generated via O—H⋯O, C—H⋯O and C—H⋯F inter­actions, and an R (2) (2)(11) motif generated by C—H⋯O and C—H⋯F inter­actions.
