) Abstract: A novel N-Pyrazolyl propanamide derivative, 3-(3-(pyridin-2-yl)-1H-pyrazol-1-yl)propanamide(1), was synthesized by Michael reaction of 3-(2-pyridinyl)pyrazole and acrylamide
The characterization of the compound was conducted by Elemental analysis, IR, MS and 1HNMR spectrum, and the crystal structure of compound 1 was determined by X-ray diffraction analysis
The X-ray single-crystal analysis show that compound 1 belongs to triclinic system with space group P -1 and a=7
