Description

Verfahren zur Herstellung von N-Carbothionverbindungen der Oxy-carboxyphenylamine bzw. ihrer Derivate Von den Oxy-carboayl)henylaminen hat in letzter Zeit das 3-Oxy-4-carboxyphenylamin für die chemotherapeutische Bekämpfung der Tuberkulose an Bedeutung gewonnen. Es wurde nun gefunden, daß auch die bislang unbekannten N-Carbothionverbindungen der allgemeinen Formel in der X Wasserstoff, ein Alkalimetall einschließlich N H4 oder einen Kohlenwasserstoffrest und R" eine R N H- oder eine R S-Gruppe (R gleich organischer Rest) oder Halogen oder Oxalkyl bedeuten, besonders wertvolle Mittel zur Bekämpfung von Infektionskrankheiten, insbesondere auch Tuberkulose, darstellen. Ihre Herstellung erfolgt durch Umsetzung von Verbindungen der Formel R'-C S-R", in der R' eine durch ein Metalläquivalent einschließlich NH4 oder einen kohlenwasserstoffrest substituierte oder unsubstituierte SH-Gruppe, Oxalkyl oder Halogen bedeutet und R" außer der Bedeutung der obengenannten Gruppe noch dieselbe Bedeutung wie R' haben kann, mit 1 bzw. 2 Mol Oxy-carboxyphenylaminen der Formel in der X die oben gekennzeichnete Bedeutung hat.

Process for the preparation of N-carbothione compounds of oxy-carboxyphenylamines or their derivatives Of the oxy-carboayl) henylamines, 3-oxy-4-carboxyphenylamine has recently gained importance for the chemotherapeutic control of tuberculosis. It has now been found that the previously unknown N-carbothione compounds of the general formula in which X is hydrogen, an alkali metal including N H4 or a hydrocarbon radical and R "is an RN H or an R S group (R is an organic radical) or halogen or oxyalkyl, particularly valuable agents for combating infectious diseases, especially tuberculosis, They are prepared by reacting compounds of the formula R'-C SR ", in which R 'denotes an SH group substituted or unsubstituted by a metal equivalent including NH4 or a hydrocarbon radical, oxalkyl or halogen and R" denotes apart from the abovementioned meanings Group can still have the same meaning as R ', with 1 or 2 moles of oxy-carboxyphenylamines of the formula in which X has the meaning indicated above.
