The Novel Ketoprofenamides: Synthesis and Spectroscopic Characterization

Abstract

Synthesis of a series of new ketoprofenamides (3a-h) is described. Amide formation was achieved by aminolysis of ketoprofen benzotriazolide (2) with various amines: primary, secondary, hydroxylamine and amino acid β-alanine. The structures of synthesized compounds were characterized by means of IR, 1H and 13C NMR spectroscopies and elemental analysis. The synthesized compounds are potential prodrugs of a well-known NSAID ketoprofen
