Description
Verfahren zur Herstellung eines Derivates des 3,4-Dihydro-1,2,4-benzothiadiazin-1,1-dioxyds Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung des 3-Dichlormethyl-6-trifluormethyl-7-sulfamyl 3,4-dihydro-1,2,4-benzothiadiazin-1,1- dioxyds der Formel
EMI0001.0004
Die neue Verbindung und deren Salze, beson ders Alkalimetallsalze, wie Natrium- oder Kalium salze, zeigen eine hohe diuretische und natriuretische Wirksamkeit und können als Heilmittel Verwendung finden, besonders in Form von pharmazeutischen Präparaten,
welche diese Verbindungen zusammen mit den pharmazeutischen organischen oder anorga nischen, festen oder flüssigen Trägersubstanzen, die für enterale, z. B. orale, oder parenterale Gabe ge eignet sind, enthalten. Für die Bildung derselben kommen solche Stoffe in Frage, die mit den neuen Verbindungen nicht reagieren, wie z. B.
Wasser, Gelatine, Milchzucker, Stärke, Stearylalkohol, Ma- gnesiumstearat, Talk, pflanzliche Öle, Benzylalko- hole, Gummi, Propylenglykol, Polyalkylenglykole oder andere bekannte Arzneimittelträger. Die phar mazeutischen Präparate können z. B. als Tabletten, Dragees, Kapseln oder in flüssiger Form als Lösun gen, Suspensionen oder Emulsionen vorliegen.
Ge gebenenfalls sind sie sterilisiert und bzw. oder ent halten Hilfsstoffe, wie Konservierungs-, Stabilisie- rungs-, Netz- oder Emulgiermittel, Salze zur Ver änderung des osmotischen Druckes oder Puffer. Sie können auch noch andere therapeutisch wertvolle Stoffe, z.
B. hypotensive Mittel, enthalten, wie Rau- wolfia- oder Veratrum-Alkaloide, beispielsweise Reserpin, Rescinnamin, Deserpidin, halbsynthetische Rauwolfia-Analoge, z. B. Syringopin, Germin oder Protoveratrin, synthetische hypotensive Mittel, z. B. Hydralazin, Dihydralazin, oder Ganglienblocker, wie Chlorisondamin.
Die neue Verbindung lässt sich erfindungsgemäss erhalten, wenn man ein 2,4-Disulfamyl-anilin der Formel
EMI0001.0045
mit einem Aldehyd der Formel C1zCH-CHO oder einem seiner funktionellen Derivate umsetzt. Vor zugsweise nimmt man die Umsetzung mit dem Aldehyd in Gegenwart einer Säure, wie einer Mine ralsäure, beispielsweise einer Halogenwasserstoff säure, z. B. Salzsäure oder Bromwasserstoffsäure oder Schwefelsäure, wenn erwünscht, in wasserfreier Form vor. Der Aldehyd kann als solcher oder in Form eines diesen Aldehyd abgebenden Mittels, z. B.
als Polymeres, oder als reaktionsfähiges funktionelles Derivat, wie in Form eines Acetals mit Alkoholen, z. B. 1,1-Dimethoxy-2,2-dichloräthan, 1,1-Diäthoxy- 2,2-dichloräthan, oder anderer funktioneller Deri vate des diesen zu Grunde liegenden 1,1-Dioxy-2,2- dichloräthans verwendet werden. Die Reaktion wird in erster Linie mit ungefähr äquivalenten Mengen der Reaktionskomponenten durchgeführt.
Durch höhere Mengen an Aldehyd werden gegebenenfalls die Ausbeuten durch Bildung von höheren Konden sationsprodukten vermindert. Verwendet man den Aldehyd in Form eines seiner reaktionsfähigen Deri vate, nimmt man die Reaktion vorzugsweise in Ge genwart einer Säure, z. B. einer der obengenannten, vor. Man kann auch in Abwesenheit oder Anwesen heit eines Kondensationsmittels, z. B. einer Base, wie eines Alkalimetallhydroxyds, z. B. Lithium-, Natrium- oder Kaliumhydroxyd, arbeiten, wobei man den Aldehyd vorzugsweise als solchen verwen det.
Die Reaktion lässt sich in Abwesenheit oder vorzugsweise in Gegenwart von Lösungsmitteln, wie eines Äthers, z. B. p-Dioxan oder Diäthylenglykol- dimethyläther, eines Alkohols, wie Methanol oder Äthanol, eines Formamids, z. B.

Before preferably taking the reaction with the aldehyde in the presence of an acid such as a mine ralsäure, for example a hydrohalic acid, z. B. hydrochloric acid or hydrobromic acid or sulfuric acid, if desired, in anhydrous form. The aldehyde can be used as such or in the form of an aldehyde releasing agent, e.g. B.
as a polymer, or as a reactive functional derivative, such as in the form of an acetal with alcohols, e.g. B. 1,1-dimethoxy-2,2-dichloroethane, 1,1-diethoxy-2,2-dichloroethane, or other functional derivatives of these underlying 1,1-dioxy-2,2-dichloroethane can be used. The reaction is carried out primarily with approximately equivalent amounts of the reaction components.
Higher amounts of aldehyde may reduce the yields due to the formation of higher condensation products. If the aldehyde is used in the form of one of its reactive Deri derivatives, the reaction is preferably carried out in the presence of an acid such. B. one of the above, before. You can unit in the absence or presence of a condensing agent such. B. a base such as an alkali metal hydroxide, e.g. B. lithium, sodium or potassium hydroxide, work, whereby the aldehyde is preferably used as such.
The reaction can be carried out in the absence or, preferably, in the presence of solvents such as an ether, e.g. B. p-dioxane or diethylene glycol dimethyl ether, an alcohol such as methanol or ethanol, a formamide, z. B. dimethylformamide, or aqueous mixtures of said solvents or water, at room or elevated tempe temperature and at normal or elevated pressure in the presence of an inert gas such as nitrogen, perform.
Depending on the reaction conditions, the new compound is obtained in free form or in the form of its salts. Metal salts obtained can e.g. B. by reaction with aqueous acidic agents such as mineral acid, e.g. B. hydrohalic acid, for example hydrochloric acid or sulfuric acid, are converted into the free connec tion. This in turn can be converted into the metal salts, such as alkali metal salts, by treating e.g.
B. with a metal hydroxide, such as sodium or potassium hydroxide, in a Lö solvent such as an alkanol, e.g. B. methanol or ethanol, or in water and then evaporate the solvent. Mono- or poly-salts can be formed.
