Abstract

Process for the preparation of derivatives of pyridylaminomethylenmalonic acid by reaction of aminopyridines with derivatives of alkoxymethylenelenonic acids, characterized in that aminopyridines are reacted together with malonic acid derivatives and a higher than stoichiometric amount of formic acid orthoesters at temperatures between 60 and 160ºC .
