Nicotinoyl chloride and aniline in tetrahydrofuran solution was stirred for 8 h at ambient temperature in the presence of a catalytic quantity of triethylamine. The reaction mixture was neutralized with a saturated aqueous sodium hydrogencarbonate solution and the resulting aqueous mixture was extracted with ethyl acetate and then concentrated under reduced pressure. Then, it was subjected to
on silica, using hexane–ethyl acetate gradients. Crystals were grown from an ethanolic solution.H atoms bonded to C were positioned geometrically and refined using a riding model with C—H bond lengths of 0.93 Å and Uiso(H) = 1.2Ueq(C). The H atom bonded to N was located from a difference Fourier map and refined isotropically.

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. |

Nicotinamides were involved in biological processes such as production of energy, the synthesis of fatty acids, cholesterol and steroids, signal transduction, and the maintenance of the integrity of the genome (de Souza et al., 2005). Nicotinamides play a major role in the prevention or delay of the onset of type 1 diabetes mellitus. They also have anti-oxidant, anti-inflammatory and anti-carcinogenic activities (Gdaniec et al., 1979; Cuffini et al., 2006).
The title compound is non planar molecule with a dihedral angle of 64.81 (1)° between the phenyl and pyridine ring. N—H···O intermolecular hydrogen bonds connect the molecules to one dimensional molecular chains along the b axis and forming a C(4) graph-set motif (Bernstein et al., 1995).
