N-(4-Methoxy-phen-yl)pivalamide.

In the title mol-ecule, C(12)H(17)NO(2), the amide (N-C=O) plane is oriented at an angle of 33.9 (1)° with respect to the aromatic ring. This is accompanied by an intra-molecular C-H⋯O hydrogen bond. The meth-oxy group lies almost in the plane of the benzene ring [C-O-C-C torsion angle = 2.7 (2)°]. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains along [010].

2-Chloro-5-nitro-aniline.

The mol-ecule of the title compound, C(6)H(5)ClN(2)O(2), is close to being planar (rms deviation = 0.032 Šfor all non-H atoms), with a maximum deviation of -0.107 (3) Šfor an O atom. In the crystal structure, inter-molecular N-H⋯O and N-H⋯N inter-actions link the mol-ecules into a three-dimensional network.

N-(4-Chloro-phen-yl)-3,4,5-trimethoxy-benzamide.

In the title compound, C(16)H(16)ClNO(4), the dihedral angle between the two aromatic rings is 67.33 (8)°. The crystal packing shows strong inter-molecular N-H⋯O hydrogen bonds that link the mol-ecules to form chains along [01].
