CA 2321237

A process for producing a pyridone derivative represented by general formula (4), characterized by reacting a compound represented by general formula (1) with a hypochlorite or hypobromite or with lead tetraacetate to give a compound represented by general formula (2) and reacting this compound with a compound represented by general formula (3). The process is preferable especially from the standpoint of safety. In said formulae, R1 represents hydrogen, alkyl, substituted alkyl, etc.; Y1 represents hydrogen, alkyl, substituted alkyl, etc.; Y2 and Y3 each independently represents hydrogen, halogeno, etc.; and L represents alkyl, substituted alkyl, etc.

Procédé de fabrication d'un dérivé de pyridone représenté par la formule générale (4), caractérisé en ce qu'on fait réagir un composé de formule générale (1) avec un hypochlorite ou un hypobromite ou avec du tétraacétate de plomb, de manière à obtenir un composé de formule générale (2), et en ce qu'on fait réagir ce composé avec un composé de formule générale (3). Ce procédé est avantageux, notamment sur le plan sécurité de mise en oeuvre. Dans les formules précitées, R?1¿ désigne un hydrogène, un alkyle, un alkyle substitué, etc.; Y?1¿ désigne un hydrogène, un alkyle, un alkyle substitué etc.; Y?2¿ et Y?3¿ désignent chacun, indépendamment, un hydrogène, un halogéno, etc.; et L désigne un alkyle, un alkyle substitué, etc.).
