Title (EN) PROCESS FOR PRODUCING OPTICALLY ACTIVE N-ALKYL-PIPERIDINE-2-CARBOXANILIDE
(FR) PROCÉDÉ DE PRODUCTION DE N-ALKYL-PIPÉRIDINE-2-CARBOXANILIDE OPTIQUEMENT ACTIF
Abstract:
(EN) Disclosed herein is a process for producing optically active 1-n-propyl-2',6'-dimethyl-2-piperidinecarboxanilide. The process comprises of reacting n-propyl pipecolate ester with 2,6-dimethylanilino magnesium halide. The 1-n-propyl-2',6'-dimethyl-2-piperidinecarboxanilide obtained according to the process is having chiral purity of more than 97%.
(FR) La présente invention concerne un procédé de production de 1-n-propyl-2',6'-diméthyl-2-pipéridinecarboxanilide optiquement actif. Le procédé comprend la réaction de l'ester de pipécolate de n-propyle avec un halogénure de 2,6-diméthylanilinomagnésium. Le 1-n-propyl-2',6'-diméthyl-2-pipéridinecarboxanilide obtenu conformément au procédé présente une pureté chirale supérieure à 97 %.
