Sun, Kai-Jin; Cai, Zhao-Sheng published the article 《Synthesis, characterization and crystal structure of 2-pyridinecarboxamide》. Keywords: pyridinecarboxamide preparation crystal mol structure.They researched the compound: Picolinamide( cas:1452-77-3 ).SDS of cas: 1452-77-3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1452-77-3) here.
The 2-pyridinecarboxamide was synthesized from 2-picoline through two-steps reaction. Initially, 2-picoline was converted into 2-cyanopyridine by ammoxidation in a stainless-steel fixed-bed reactor at 370°C with V2O5 loaded on TiO2 as catalyst. The 2-cyanopyridine was transformed into 2-pyridinecarboxamide through oxidation hydrolysis in basic solution using MnO2 as oxidant at 70°C. The crystal structure of 2-pyridinecarboxamide was investigated using X-ray diffraction and SHELX 2018/3 (sh) software and the result indicated that 2-pyridinecarboxamide crystallized in the monoclinic system, space group P21/n with a = 5.207(2), b = 7.097(3), c = 16.243(6) Å, V = 595.7 (4) Å3; Z = 4.
