Title (EN) 4-HETEROARYL PIPERIDINE INTERMEDIATES AND THEIR PREPARATION
(FR) INTERMEDIAIRES DE 4-HETEROARYLE PIPERIDINE ET LEUR PREPARATION
Abstract:
(EN) This invention relates to new compounds of formulae (I, II) in which X is O, S, or NR where R is H or C1-4-alkyl, Z is hydrogen, halogen, trifluoromethyl, C1-8-alkoxy, C1-8-alkyl straight or branched, nitro, C2-8-alkenyl, or a C1-4-alkyl mono- or disubstituted amino group, R1 is H or straight or branched C1-8-alkyl. The invention also relates to a method of preparing a compound of formulae (I and II).
(FR) Nouveaux composés selon les formules (I et II) dans lesquelles X représente O, S, ou NR où R représente H ou alkyle contenant 1 à 4 atomes de carbone, Z représente hydrogène, halogène, trifluorométhyle, alcoxy contenant 1 à 8 atomes de carbone, alkyle à chaîne droite ou ramifiée contenant 1 à 8 atomes de carbone, nitro, alcényle contenant 2 à 8 atomes de carbone, où un groupe alkyle contenant 1 à 4 atomes de carbone à monosubstitution ou à disubstitution, R1 représente H ou alkyle à chaîne droite ou ramifiée contenant 1 à 8 atomes de carbone. L'invention concerne également un procédé de préparation d'un composé selon les formules (I et II).
