N-(2-Aminopyridin-3-yl)-4-methyl-N-(4-methylphenylsulfonyl)benzenesulfonamide

A. Taher and V. J. Smith

Abstract: The title compound, C₁₉H₁₉N₃O₄S₂, was prepared by the reaction of 2,3-diaminopyridine with tosyl chloride in a mixture of dichloromethane-pyridine as solvent. In the crystal, molecules associate via pairs of N-HN hydrogen bonds, forming a centrosymmetric eight-membered {HNCN}₂ synthon. The dihedral angles between the aminopyridine ring and the tosyl benzene rings are 50.01 (6) and 32.01 (4)°.
