In (I), the N-H and C=O bonds in the C-NH-C(O)-C segment are anti to each other, similar to that observed in N-(4-chlorophenyl)-benzamide (II) (Gowda et al., 2008).
The dihedral angle between the two benzene rings is 59.6 (1)°, compared to the value of 60.8 (1)° in (II).
The packing of molecules linked by N-H···O hydrogen bonds into infinite chains is shown in Fig. 2.

Experimental
The title compound was prepared according to the method described by Gowda et al. (2003). The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra. Rod-like colourless single crystals of the title compound were obtained by slow evaporation from an ethanol solution of the compound (0.5 g in about 30 ml of ethanol) at room temperature.
