Abstract
A találmány tárgya eljárás (I) általános képletű 1-alkil-, különösen1,3-dialkil-pirazol-5-karbonsavészterek előállítására 2,4-dikarbonsavészterek-enolátból és N-alkil-hidrazíniumsókból. Az (I)általános képletben R1 és R4 jelentése egymástól függetlenül egyenesvagy elágazó szénláncú C1-C6-alkilcsoport, C3-C7-cikloalkilcsoportvagy adott esetben szubsztituált C7-C12-aralkilcsoport és R2 és R3jelentése egymástól függetlenül hidrogénatom, egyenes vagy elágazószénláncú C1-C6-alkilcsoport, C3-C7-cikloalkilcsoport vagy adottesetben szubsztituált C7-C12-aralkilcsoport. Az eljárásra jellemző,hogy egy (II) általános képletű 2,4-diketokarbonsavészterenolátot,amelynek képletében M jelentése fématom egy ekvivalense - oldószer ésvíz jelenlétében egy (III) általános képletű N-alkil-hidrazíniumsóval- e képletben R5 a COOq-résszel együtt szerves sav anionját jelenti -reagáltatnak.
