Description
<EMI ID=1.1> des procédés pour leur préparation. Les composés suivant l'invention peuvent se présenter sous forme de sels d'addition" mais <EMI ID=2.1> Une hypothèse depuis longtemps admise est que beaucoup des substances à activité physiologique se combinent dans le <EMI ID=3.1> <EMI ID=4.1> mais .comme ses activités sont de plusieurs genres, l'on suppose qu'il existe plusieurs types de récepteurs d'histamine. Le genre <EMI ID=5.1> <EMI ID=6.1> le fait qu'ils agissent comme récepteurs d'histamine d'une autre <EMI ID=7.1> les composés'faisant l'objet de l'invention peuvent être représentés par la formule. générale ci-après ? étant entendu que <EMI ID=8.1> <EMI ID=9.1> <EMI ID=10.1> <EMI ID=11.1> <EMI ID=12.1> le, bensyle, un atome d'halogène, un groupe amino ou un groupe <EMI ID=13.1> du groupe A un autre noyau, par exemple un noyau.benzène ou pyrimidine, ou un noyau partiellement insaturé ; 1 et m sont des nom- <EMI ID=14.1> un groupe nitro ou cyano.

Le premier stade de cette préparation consiste à faire <EMI ID=24.1> <EMI ID=25.1> <EMI ID=26.1> Lorsque Q est un halogène, cette réaction peut être ef- fectuée dans des conditions fortement basiques, par exemple en présence d'éthoxyde de sodium ou d'hydroxyde de sodium. Puisque le composé de la formule III est uns amine primaire, il est nécessaire de protéger le groupe amino, par exemple par un groupe phtal-imido, qui peut ensuite être séparé par hydrolyse acide ou <EMI ID=27.1> la réaction s'effectue dans des conditions acides, par exemple en présence d'un acide halohydrique, tel qu'une solution aqueuse à <EMI ID=28.1> l'acide acétique glacial. Lorsque Q est un radical méthoxy, la réaction peut également s'effectuer en présence d'une solution <EMI ID=29.1> Les produits obtenus par les procédés si-dessus sont des composés de la formule suivante , ou encore les sels d'addition . <EMI ID=30.1> <EMI ID=31.1> <EMI ID=32.1> 3.' on fait réagir dans un solvant approprié, tel que le chloroforme, avec, un isothiocyanate d'acyle.
