De nye forbindelser som fremstilles ved fremgangsmåten ifølge oppfinnelsen er for-delaktige kjemoterapeutiske forbindelser og har anvendelse bl. a. ved behandling av glaucoma (grønn stær). Forbindelsene har di-uretiske eller natriuretiske egenskaper. as well as alkali metal salts of such compounds. In the above-mentioned formula, R denotes a chlorine or bromine atom. The new compounds produced by the method according to the invention are advantageous chemotherapeutic compounds and are used, among other things, a. in the treatment of glaucoma (glaucoma). The compounds have diuretic or natriuretic properties.

vanlige måter, f. eks. i form av tabletter. Forbindelsene er effektive ved oral anvendelse, såvel som ved injeksjon. Da for-bindelsenes alkalimetallsalter er lett opp-løselige i isotoniske, vandige midler, kan usual ways, e.g. in the form of tablets. The compounds are effective by oral application, as well as by injection. As the compounds' alkali metal salts are easily soluble in isotonic, aqueous media, can

som, om ønskes, kan tilsettes konserve-ringsmidler. to which, if desired, preservatives can be added.
Dosene av 4-klorbenzen-l,3-disulfonamid-forbindelsen som fremstilles ved The doses of the 4-chlorobenzene-1,3-disulfonamide compound produced by
fremgangsmåten ifølge foreliggende oppfinnelse kan varieres innen et stort områ- the method according to the present invention can be varied within a large area
de. Av denne grunn kan tabletter inne-holdende 100, 150, 250 eller 500 mg av den aktive bestanddel gjøres tilgjengelig for legene for symptomatisk innstilling av do-sen etter den enkelte pasient. De nevnte doser ligger godt under den giftige eller dødelige dose for forbindelsene. Studier av kronisk giftighet med hunder som for-søksdyr og under ani? ;ndelse av 4,5-diklor-benzen-l,3-disulfonar"aid viser at 20 mg pr. kg pr. døgn tåles godt i lange tidsrom uten noen uønskede toksiske virkninger. Ved for-søk med mus ble den dose som fremkalte en dødelighet på 50 % (LD50) funnet å være 703 mg pr. kg ved intravenøs anvendelse, og 1710 mg pr. kg ved oral anvendelse. the. For this reason, tablets containing 100, 150, 250 or 500 mg of the active ingredient can be made available to doctors for symptomatic adjustment of the dose according to the individual patient. The mentioned doses are well below the toxic or lethal dose for the compounds. Studies of chronic toxicity with dogs as test animals and during ani? A study of 4,5-dichloro-benzene-1,3-disulfonamide shows that 20 mg per kg per day is well tolerated for long periods of time without any unwanted toxic effects. In experiments with mice, the dose that induced a 50% lethality (LD50) found to be 703 mg per kg by intravenous application, and 1710 mg per kg by oral application.
Fremgangsmåten ifølge oppfinnelsen til fremstilling av 4-klor-5-halogenbenzen-1,3-disulfonamid-forbindelser er karakterisert ved at man omsetter et 5-halogen-4-hydroxybenzen-l,3-disulfonylklorid med fosforpentaklorid, hvorved der dannes det tilsvarende 4-klor-5-halogenbenzen-l,3-disulfonylklorid, som man på kj ent måte overfører til det tilsvarende 4-klor-5-halo-genbenzen-l,3-d'isulfonamid, i hvilket 5-halogensubstituenten er et kloratom eller et bromatom, og eventuelt på kjent måte danner de tilsvarende alkalimetallsalter. The process according to the invention for the production of 4-chloro-5-halobenzene-1,3-disulfonamide compounds is characterized by reacting a 5-halo-4-hydroxybenzene-1,3-disulfonyl chloride with phosphorus pentachloride, whereby the corresponding 4 -chloro-5-halobenzene-1,3-disulfonyl chloride, which is transferred in a known manner to the corresponding 4-chloro-5-halobenzene-1,3-disulfonamide, in which the 5-halogen substituent is a chlorine atom or a bromine atom, and possibly in a known manner they form the corresponding alkali metal salts.
Fortrinnsvis bruker man 2,5 mol fosforpentaklorid pr. mol disulfonylklorid. Preferably, 2.5 mol of phosphorus pentachloride is used per moles of disulfonyl chloride.
Alkalimetallsaltene av 4-klor-5-halo-genbenzen-l,3-disulfonamid-forbindelsene fremstillet ved fremgangsmåten ifølge oppfinnelsen kan fremstilles ved å oppløse vedkommende forbindelse i en vandig eller en alkoholisk oppløsning av vedkommende al-kalimetallhydroksyd, og om ønskes å iso- eller ved hjelp av andre metoder som er lere saltet ved fordampning av oppløsnings- kjent for fagfolk i den organiske kjemi, midlet. Et hvilket som helst alkalimetall- I det følgende beskrives som eksempler salt som natrium, kalium eller litiumsalter noen utførelsesformer for fremgangsmåten kan fremstilles ved hjelp av denne metode, ifølge oppfinnelsen. The alkali metal salts of the 4-chloro-5-halo-benzene-1,3-disulfonamide compounds produced by the method according to the invention can be prepared by dissolving the compound in question in an aqueous or an alcoholic solution of the alkali metal hydroxide in question, and if desired to iso- or by means of other methods which are clay salted by evaporation of solvent- known to those skilled in organic chemistry, the agent. Any alkali metal - In the following, salt such as sodium, potassium or lithium salts are described as examples, some embodiments of the method can be prepared using this method, according to the invention.
En blanding av 5-klor-4-hydroksyben-zen-l,3-disulfonylklorid (omkring 302 g tilsvarende 0,92 mol) og 480 g (2,3 mol) fosforpentaklorid oppvarmes i en time til 120— 140° C i en to liters rundkolbe. Den herved erholdte klare oppløsning helles på is, hvorved 4,5-diklorbenzen-l,3-disulfonyl-klorid øyeblikkelig skiller seg ut som et fast stoff. Dette faste stoff oppsamles ved filtrering og vaskes med vann. Mens det ennå er i fuktig tilstand tilsettes det i porsjoner og i løpet av 20 minutter til en liter konsentrert ammoniakkvann i et 3 liters beger-glass omgitt av et koldt vannbad. Man lar derpå reaksjonsblandingen stå i en time uten avkjøling, hvorpå den oppvarmes på dampbad i omkring 30 minutter mens luft bobles gjennom den for å fjerne noe av overskuddet av ammoniakk. Reaksjonsblandingen filtreres derpå, surgjøres med konsentrert saltsyre og avkjøles. Produktet skiller seg ut som et gummiaktig stoff fra hvilket den overliggende væske dekanteres. Det gummiaktige stoff tritureres derpå med 250 ml vann for å frembringe krystallisa-sjon. Det således erholdte rå produkt om-krystalliseres fra 3200 ml kokende vann og derpå fra 40 %'s vandig isopropylalkohol, hvorpå man får 4,5-diklorbenzen-l,3-disulfonamid som et hvitt fast stoff med sm.p. 228,5—229,0° C. Eksempel 2: 5- brom- 4- klort>enzen- l, 3- disulfonamid. A mixture of 5-chloro-4-hydroxybenzene-1,3-disulfonyl chloride (about 302 g corresponding to 0.92 mol) and 480 g (2.3 mol) phosphorus pentachloride is heated for one hour to 120-140° C in a two liter round flask. The clear solution thus obtained is poured onto ice, whereby 4,5-dichlorobenzene-1,3-disulfonyl chloride immediately separates out as a solid. This solid is collected by filtration and washed with water. While still moist, it is added in portions and over 20 minutes to one liter of concentrated ammonia water in a 3 liter beaker surrounded by a cold water bath. The reaction mixture is then allowed to stand for one hour without cooling, after which it is heated on a steam bath for about 30 minutes while air is bubbled through it to remove some of the excess ammonia. The reaction mixture is then filtered, acidified with concentrated hydrochloric acid and cooled. The product separates as a gummy substance from which the overlying liquid is decanted. The gummy substance is then triturated with 250 ml of water to produce crystallization. The crude product thus obtained is recrystallized from 3200 ml of boiling water and then from 40% aqueous isopropyl alcohol, whereupon 4,5-dichlorobenzene-1,3-disulfonamide is obtained as a white solid with m.p. 228.5—229.0° C. Example 2: 5-bromo-4-chlorotriene-1,3-disulfonamide.
Ved i stedet for det i eksempel 1 an-vendte 5-klor-4-hydroksybenzen-l,3-disulfonylklorid å bruke en ekvimolar mengde 5-brom-4-hydrofcsyibenzen-l,3-disulfonid-klorid og forøvrig igå frem således som beskrevet i eksempel 1 får man 5-brom-4-klorbenzen-l,3-disulfonamid. By instead of the 5-chloro-4-hydroxybenzene-1,3-disulfonyl chloride used in example 1, using an equimolar amount of 5-bromo-4-hydroxybenzene-1,3-disulfonide chloride and otherwise proceeding as follows described in example 1, 5-bromo-4-chlorobenzene-1,3-disulfonamide is obtained.
