1-Naphthalene acetic acid (0.186 g, 1 mmol), 4-chloroaniline (0.127 g, 1 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (1.0 g, 0.01 mol) were dissolved in dichloromethane (20 ml). The mixture was stirred in presence of triethylamine at 273 K for about 3 h. The contents were poured into 100 ml of ice-cold aqueous hydrochloric acid with stirring, which was extracted thrice with dichloromethane. Organic layer was washed with saturated NaHCO3 solution and brine solution, dried and concentrated under reduced pressure to give the title compound. Colourless blocks were grown from acetone and toluene (1:1) mixture by the slow evaporation method (m.p. 449–451 K).
Atom H1N1 was located in a difference Fourier map and refined freely with N1—H1N1 = 0.98 (5) Å. The remaining H atoms were positioned geometrically and refined using a riding model with C—H = 0.93 or 0.97 Å and Uiso(H) = 1.2Ueq(C).
In continuation of our work on synthesis of

Bond lengths are comparable to related structures (Fun et al., 2010, 2011a,b, 2012). The naphthalene ring system (C1–C10, maximum deviation of 0.014 (9) Å at atom C5) forms a dihedral angle of 74.8 (2)° with the benzene ring (C13–C18).

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 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 > 2sigma(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. |

In continuation of our work on synthesis of amides (Fun et al., 2010, 2011a,b, 2012), we report herein the crystal structure of the title compound.
The molecular structure is shown in Fig. 1. Bond lengths are comparable to related structures (Fun et al., 2010, 2011a,b, 2012). The naphthalene ring system (C1–C10, maximum deviation of 0.014 (9) Å at atom C5) forms a dihedral angle of 74.8 (2)° with the benzene ring (C13–C18).
In the crystal structure, Fig. 2, molecules are linked via N1—H1N1···O1 hydrogen bonds (Table 1) into one-dimensional chains along [010].
