Description

Verfahren zur Darstellung von substituierten p, p'-Diaminodiphenylsulfonen Das p, p'-Diaminodiphenylsulfon ist bekannt als 'ausgezeichnetes Mittel zur Bekämpfung von Streptokokken- und Pneumokokkeninfektionen, doch besitzt es den Nachteil einer allzu großen Toxizität, so daß von seiner klinischen Verwendung Abstand genommen werden mußte. Man hat versucht, diesen Nachteil zu beheben durch Überführung des Sulfons in seine Acylderivate, insbesondere in seine Diacetylderivate, oder auch in Umsetzungsprodukte mit Aldehyden (Schifische Basen), ohne jedoch damit eine Entgiftung in ausreichendem Maße zu erzielen.Process for the preparation of substituted p, p'-diaminodiphenyl sulfones The p, p'-diaminodiphenyl sulfone is known to be an excellent control agent of strep and pneumococcal infections, but it has the disadvantage of one too great toxicity, so that its clinical use was refrained from had to become. Attempts have been made to remedy this disadvantage by transferring the Sulphone into its acyl derivatives, especially into its diacetyl derivatives, or else in reaction products with aldehydes (ship's bases), but without detoxification to a sufficient extent.

Es wurde nun gefunden, daß man eine solche Entgiftung des p, p'-Diaminodiphenylsulfons erreichen kann, ohne seine Wirksamkeit bei bakteriellen Infektionen im geringsten herabzusetzen, wenn man das Sulfon mit Formaldehyd in Gegenwart von Alkoholen, zweckmäßig bei gewöhnlicher Temperatur, umsetzt. Man erhält dann Verbindungen der Formel in der R einen Alkylrest, insbesondere einen aliphatischen Alkylrest bedeutet.It has now been found that such a detoxification of p, p'-diaminodiphenyl sulfone can be achieved without reducing its effectiveness in bacterial infections in the least, if the sulfone is reacted with formaldehyde in the presence of alcohols, expediently at ordinary temperature. Compounds of the formula are then obtained in which R denotes an alkyl radical, in particular an aliphatic alkyl radical.

Für die Durchführung des Verfahrens seien folgende Beispiele gegeben: Beispiel i ioo g p, p'-Diaminodiphenylsulfon werden Init Zoo ccm 95 prozentigen Äthylalkohol und 30o ccm 35prozentigen Formaldehydlösung io Stunden bei Raumtemperatur gesebüttelt. Das gebildete Kondensationsprodukt fällt aus der Uisinig in kristalliierter Form aus und wird zur Reinigung mehrmals aus Äthanol timkrist2illisiert. Schmelzpunkt 148 his i 5o unter geringer Zersetzung. Aus- beute cgo °j" der Theorie. 1-,'eispiel2 io g p. p'-Diaminodiplieiivlsulfon werden . finit ioo ccm 1Ietlianol und 5o ccm Forin-,h aldehvdlösung wie in Beispiel i geschüttelt: Das ausgeschiedene Kristallisat wird aus Äthanol umgelöst. Schmelzpunkt i-.o bis i-lj-'. Ausbeute 9o °f, der Theorie. Die Kondensation findet auch bei höherer Temperatur statt und ist an Stelle von Äthanol und Methanol auch init höher niole- kularen Alkoholen ausführbar. Die erhaltenen Kondensation sprodul:te sind gut verträglich und weit weniger toxisch als die bislang für dieses therapeutische Gebiet bekannten Abköimnlinge des Diaininocliplie- nvlsulfons, z. R. das Diacetvldiaminodi- I)helivlsulfon. The following examples are given for carrying out the process: Example 100 gp, p'-diaminodiphenylsulfone are shaken at room temperature for 10 cc of 95 percent ethyl alcohol and 30 cc of 35 percent formaldehyde solution. The condensation product formed falls from the Uisinig in crystallized form and is used for cleaning several times Time-crystallized ethanol. Melting point 148 up to i 50 with little decomposition. The end- booty cgo ° j "of the theory. 1 -, 'example2 io g p. p'-Diaminodiplieiivlsulfon be. finite 100 ccm 1Ietlianol and 5o ccm Forin-, h Aldehyde solution shaken as in example i: The precipitated crystals become out Dissolved ethanol. Melting point i-.o to i-lj- '. Yield 9o ° f, the theory. The condensation takes place even at higher Temperature instead of and is in place of Ethanol and methanol also with higher Cular alcohols executable. The condensation obtained is brittle well tolerated and far less toxic than those so far for this therapeutic area known descendants of the Diaininocliplie- nvlsulfons, e.g. R. the diacetvldiaminodi- I) helivlsulfone.
