Synthesis and structural studies of 6-(2,5-dimethyl-1h-pyrrol-1-yl)pyridin- 2-amine

Abstract

6-(2,5-Dimethyl-1H-pyrrol-1-yl)pyridin-2-amine (1) was synthesized and characterized by elemental analyses, 1H-NMR and 13C-NMR, FTIR, Uv-Vis, mass spectral studies and single-crystal X-ray diffraction. All data obtained from spectral studies support the structural properties of 1. Intermolecular N-H?N hydrogen bonds produce an R2 2(8) ring. An extensive three-dimensional network formed by C-H?? and N-H??-facial hydrogen bonds is responsible for the crystal stabilization. The combination of C-H?? interactions produces R33(12), R43(19) and R 44(20) rings.
