Supplementary data and figures for this paper are available from the IUCr electronic archives (Reference: SJ5116). We report here in the crystal structure of the title compound, methyl 2-amino-5-chlorobenzoate. In the molecule of the title compound ( Fig. 1), the bond lengths (Allen et al., 1987) and angles are within normal ranges. In the crystal structure, intermolecular C-H1A···O2 hydrogen bonds link the molecules into zig-zag chains along the c axis, to form a stable structure ( Fig. 2).

Experimental
The title compound, methyl 4-(3-chloropropoxy)benzoate was prepared by a literature method (Jaseer et al. 2010). Crystals suitable for X-ray analysis were obtained by slow evaporation of an ethyl acetate solution.

Refinement
H atoms were positioned geometrically, with C-H = 0.93, 0.97 and 0.96 Å for aromatic, methylene and methyl H atoms, respectively, and constrained to ride on their parent atoms, with U iso (H) = xU eq (C,N), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

Special details
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > 2sigma(F 2 ) is used only for calculat-supplementary materials sup-3 ing R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
