Abstract

La présente invention concerne des 9-(2,6-dihalogénobenzyl) adénines sensiblement exemptes du 3-isomère ainsi que leur préparation et leur purification. L'un des procédés de préparation de ces composés consiste à alcoyler un sel d'adénine avec des halogénures de 2,6-dihalogénobenzyle dans un système à deux phases en présence d'un catalyseur de transfert de phase et à traiter ensuite le mélange résultant d'isomères de position, contenant principalement le 9-isomère désiré contaminé par des quantites importantes du 3-isomère mutagène, en désalcoylant selectivement le 3-isomère avec de l'acide sulfurique en présence d'un piège à ions carbénium pour obtenir le 9-isomère sensiblement exempt du 3-isomère. Les adénines ainsi obtenues sont utiles comme agents de traitement et de prévention de la coccidiose chez la volaille.The present invention relates to substantially 3-isomer-free 9- (2,6-dihalobenzyl) adenines and their preparation and purification. One of the methods of preparing these compounds is to alkylate an adenine salt with 2,6-dihalobenzyl halides in a two-phase system in the presence of a phase transfer catalyst and then process the resulting mixture. of positional isomers, mainly containing the desired 9-isomer contaminated with significant amounts of the mutagenic 3-isomer, by selectively dealkylating the 3-isomer with sulfuric acid in the presence of a carbenium ion trap to obtain 9 -isomer substantially free from the 3-isomer. The adenines thus obtained are useful as agents for the treatment and prevention of coccidiosis in poultry.
