Wird diazotiertes Aminoazotoluol mit p-Aminobenzoesäurealkylestern oder p-Oxybenzoesäurealkylestern umgesetzt, so erhält man therapeutisch wichtige Verbindungen, welche in der Wund- und Hautbehandlung Anwendung finden sollen.Is diazotized aminoazotoluene with p-aminobenzoic acid alkyl esters or p-oxybenzoic acid alkyl esters reacted, therapeutically important compounds are obtained, which to be used in wound and skin treatment.
p-Aminobenzoesäureester führen hierbei zu Diazoaminokörpern, Verbindungen, welche bislang eine therapeutische Verwendung nichtp-aminobenzoic acid esters lead to diazoamino bodies, compounds that have hitherto been used no therapeutic use
ίο gefunden haben. Die nach untenstehendem Beispiel I erhaltene Verbindung aus diazotiertem Aminoazotoluol mit p-Aminobenzoesäureäthylester besitzt als ein in der Aminogruppe substituiertes Anästhesin noch wahrnehmbare anästhesierende Eigenschaften. Der neue Arzneikörper erzeugt auf der Zunge bei längerer Berührung ein stumpfes Gefühl der Unempfindlichkeit.ίο have found. The below Example I compound obtained from diazotized aminoazotoluene with ethyl p-aminobenzoate possesses an anesthetic that is substituted in the amino group, which is still perceptible anesthetic properties. The new medicinal body produces on the tongue at prolonged touch a dull feeling of insensitivity.
Mit p-Oxybenzoesäureestern führt diazotiertes Aminoazotoluol zu Azofarbstoffen, Verbindungen, welche ihrer Konstitution nach als in der Aminogruppe substituierte Orthoforme, und zwar m-Amino-p-oxybenzoesäureester aufzufassen sind. Sie besitzen ebenfalls anästhesierende Eigenschaften. Der nach Beispiel II erhaltene Farbstoff aus ρ - Oxybenzoesäureäthylester hat einen zunächst schwach brennenden Geschmack und ruft alsdann auf der Zunge ein etwas stumpfes Gefühl hervor.. Vor dem bisher gebräuchlichen Scharlachrot R medicinale (Aminoazotoluolazo-ß-naphtol) zeichnen sich demnach die vorgenannten neuen Verbindungen durch diese anästhesierenden Eigenschaften, welche sich zu den bekannten epithelisierenden Wirkungen zugesellen, vorteilhaft aus. .With p-oxybenzoic acid esters, diazotized aminoazotoluene leads to azo dyes, compounds, which according to their constitution as orthoforms substituted in the amino group, and although m-amino-p-oxybenzoic acid esters are to be understood. They also have anesthetics Properties. The dye obtained according to Example II from ρ - ethyl oxybenzoate has an initially weakly burning taste and then produces a somewhat dull feeling on the tongue the previously common scarlet red R medicinale (Aminoazotoluolazo-ß-naphtol) draw Accordingly, the aforementioned new compounds are characterized by these anesthetic properties, which are associated with the known epithelializing effects, advantageous the end. .
22,5 g Aminoazotoluol, in bekannter Weise diazotiert, werden einer wässerigen Anreibung oder alkoholischen Lösung von 16,5 g p-Aminobenzoesäureäthylester zugegeben und die Umsetzung durch allmählichen Zusatz von Natriumacetatlösung oder Natriumbicarbonat bis zur schwach sauren oder neutralen Reaktion gefördert. Nach beendeter Umsetzung wird schwach alkalisch gemacht, der Niederschlag abgesaugt, gewaschen und bei niedriger Temperatur getrocknet.22.5 g of aminoazotoluene, diazotized in a known manner, are an aqueous grind or alcoholic solution of 16.5 g of ethyl p-aminobenzoate was added and the reaction by gradually adding sodium acetate solution or sodium bicarbonate up to promoted to a weakly acidic or neutral reaction. After implementation is complete Made weakly alkaline, the precipitate filtered off with suction, washed and kept at low temperature dried.
Die so erhaltene Diazoaminoverbindung aus Aminoazotoluol und p-Aminobenzoesäureäthylester ist ein schwarzbraunes Pulver, unlöslich in Wasser, dagegen mit gelbbrauner Farbe löslich in Alkohol, Äther und fetten ölen.The diazoamino compound thus obtained from aminoazotoluene and ethyl p-aminobenzoate is a black-brown powder, insoluble in water, but with a yellow-brown color soluble in alcohol, ether and fats oils.
