A facile regioselective synthesis of (5-amino-4-cyano-1H-imidazol-1-yl) benzoic acids

Barros, Siria A.,Goncalves, M. Sameiro T.,Oliveira-Campos, Ana M. F.,Proenca, Fernanda R. P.

, p. 13 - 19 (2008/09/18)

(Chemical Equation Presented) A simple and efficient method was developped for the synthesis of 3-(5-amino-4-cyano-1H-imidazol-1-yl)-4-substituted benzoic acids 3. These compounds were isolated by intramolecular cyclisation of the corresponding 3-{[(Z)-2-amino-1,2-dicyano-vinyl]amino}methyleneaminobenzoic acids in the presence of base.
