Abstract

La présente invention se rapporte à un nouveau procédé de préparation de composés représentés par la formule générale (I), (où R1 et R3 représentent un hydrogène ou un alkyle C¿1-4, R?2 représente un alkyle C¿1-4? et R?4, R5 et R6¿ représentent un hydrogène ou un halogène), ainsi qu'à des sels pharmaceutiquement acceptables de tels composés. Ledit procédé consiste à faire réagir un composé représenté par la formule générale (II), (où R représente un halogène ou un groupe acyloxy aliphatique contenant de 2 à 6 atomes de carbone ou un groupe acyloxy aromatique contenant 7 à 11 atomes de carbone et R?4, R5 et R6¿ sont définis ci-dessous), avec un dérivé de pipérazine représenté par la formule générale (III), (où R?1, R2 et R3¿ sont définis ci-dessus), ou avec un sel de ce dérivé, puis à soumettre le composé ainsi obtenu, qui est représenté par la formule générale (IV), (où R, R?1, R2 et R3¿ sont définis ci-dessus) à une opération d'hydrolyse après ou sans isolement, et, si on le désire, à convertir le composé représenté par la formule générale (I) ainsi obtenu en un de ses sels ou à libérer ce composé de son sel. Les composés représentés par la formule générale (I) sont des agents antibactériens connus. Le procédé de la présente invention a l'avantage de rendre simple la préparation des composés désirés de formule générale (I), tout en se caractérisant par des rendements élevés et un temps de réaction court.
