In the title compound, C18H13ClFN3O2, the pyrrolidine ring adopts an and the planar part is rotated by 4.3 (6)° from the plane of the benzene ring and is almost perperdicular both to the diazoacetyl unit [dihedral angle = 78.93 (7)°] and the phenyl ring [dihedral angle = 86.07 (7)°]. In the crystal, molecules are linked into a three-dimensional framework by C—H⋯O interactions. The molecular conformation is stabilized by an intramolecular C—H⋯O hydrogen bond.

The title compound was synthesized from the corresponding γ-lactam carboxylic acid which, in turn, was prepared following the general method (Ray et al. 1994, 1998) developed in our laboratory, through the reaction of its acid chloride with diazomethane. Single crystal was grown by dissolving the compound in mixture (n-hexane-ethylacetate) solvent and then by slow evaporation technique at room temperature. It is a yellow colour solid; m.p. 407–409 K (n-hexane-ethylacetate).
Hydrogen atoms were found in subsequent difference Fourier maps and included in observed positions and refined as free isotropic atoms.
A view of the molecule with numbering scheme is shown in Figure 1. In the title compounnd (I) , bond distances and angles are within normal ranges (Allen, 2002) .The atoms of the chain contaning the diazo group are planar [max deviation 0.339 (9)Å for N1].The pyrrolidin ring adopts an φ2 = 115.6 (2)°(Cremer & Pople, 1975). The 3-chloro-4-fluoro-benzene ring and the best plane of pyrrolidin ring defined by C10\N1\C9\C8 atoms are almost coplanar [4.20 (7)°]. The phenyl ring and the acetyl group O2/C10/C17/C18 fragment (r.m.s. deviation 0.023 Å) are almost perpendicular to plane defined by the N1/C8/C9/C10/C11/C12/C13/C14/C15/C16 atoms (r.m.s. deviation 0.038 Å) [87.07 (5); 88.46 (3)° respectively]. In the crystal molecules are linked by C—H···O interactions [C···O range 3.2320 (16)-3.3445 (19) Å; C—H···O range 136-157°] and these link the molecules into a three-dimensional framework. The is stabilized by one intramolecular C—H···O hydrogen bond (Table 1). As shown in Figure 2, carbonyl oxygen O2 interacts with three H atoms (C10—H10···O2, C16—H18···O2, and C18—H18···O2), which regarding crystal packing could be classified as supportive (Desiraju, 2005).

Experimental. Data was collected using a X8 APEX II BRUKER-Nonius diffractometer equipped with an KYROFLEX low-temperature apparatus operating at 100 K. A suitable crystal was chosen and mounted on Mitegen MicroMount (radiation-hard polymer). Data were measured using omega scans of 0.5° per frame for 10 s, such that a total of 1280 frames were collected in a optimized strategy and with a final resolution of 0.75 Å. Data integration and reduction was performed using the Apex2 (Bruker Nonius, 2005) suite software. Absorption corrections were applied using SADABS (2004) of the suite software. The structures are solved by the direct method using the SHELX97 program and refined by least squares method on F2 SHELXL97, incorporated in the Apex2 suite software. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. All non-hydrogen atoms were refined anisotropically. Hydrogen were found in subsequent difference Fourier maps and included in observed positions and refined as free isotropic atoms. |

A view of the molecule with numbering scheme is shown in Figure 1. In the title compounnd (I) , bond distances and angles are within normal ranges (Allen, 2002) .The atoms of the chain contaning the diazo group are planar [max deviation 0.339 (9)Å for N1].The pyrrolidin ring adopts an envelope conformation with puckering parameters q2 = 0.2816 (12) Å and φ2 = 115.6 (2)°(Cremer & Pople, 1975). The 3-chloro-4-fluoro-benzene ring and the best plane of pyrrolidin ring defined by C10\N1\C9\C8 atoms are almost coplanar [4.20 (7)°]. The phenyl ring and the acetyl group O2/C10/C17/C18 fragment (r.m.s. deviation 0.023 Å) are almost perpendicular to plane defined by the N1/C8/C9/C10/C11/C12/C13/C14/C15/C16 atoms (r.m.s. deviation 0.038 Å) [87.07 (5); 88.46 (3)° respectively]. In the crystal molecules are linked by C—H···O interactions [C···O range 3.2320 (16)-3.3445 (19) Å; C—H···O range 136-157°] and these link the molecules into a three-dimensional framework. The molecular conformation is stabilized by one intramolecular C—H···O hydrogen bond (Table 1). As shown in Figure 2, carbonyl oxygen O2 interacts with three H atoms (C10—H10···O2, C16—H18···O2, and C18—H18···O2), which regarding crystal packing could be classified as supportive (Desiraju, 2005).
