3-Amino-N-benzyl-6-(4-fluorophenyl)thieno[2,3-b]pyridine-2-carboxamide

J.-N. Zhao, S.-Y. Yang and L. Yang

Abstract: In the title compound, C₂₁H₁₆FN₃OS, the thieno[2,3-b]pyridine system forms dihedral angles of 10.57 (12) and 83.87 (5)° with the fluorophenyl ring at the 6-position and the phenyl ring of the benzyl group, respectively. In the crystal, molecules are linked by weak N-HN anf N-HO hydrogen bonds and - stacking interactions involving fluorophenyl rings of adjacent molecules, with a centroid-centroid distance of 3.648 (10) Å. In addition, intramolecular N-HS and N-HO hydrogen bonds contribute to the stability of the molecular conformation.
