Abstract

Process for preparing picolinic acid derivatives of the general formula I ** (See formula) ** in which X means the cyano radical -CN or the carbamoyl radical -CO-NH2, characterized by acting on an alpha-amino-2-furanacetic acid derivative corresponding to general formula II ** (See formula) ** in which And it means the cyano radical and at the same time z means hydrogen or the carbamoyl radical, or And it means the radical carbamoyl and at the same time Z means hydrogen, or last Y and Z together mean the imidodicarbonyl radical -CO-NH-CO-, chlorine or bromine in an acid medium containing water.
