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, (1)H-NMR and (13)C-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 center dot center dot center dot N hydrogen bonds produce an R(2)(2)(8) ring. An extensive three-dimensional network formed by C-H center dot center dot center dot pi and N-H center dot center dot center dot pi-facial hydrogen bonds is responsible for the crystal stabilization. The combination of C H g interactions produces R(3)(3)(12), R(4)(3)(19) and R(4)(4)(20) rings.
