In der Phenacetinreihe sind bisher in der Alkylgruppe hydroxylierte Derivate der O-alkylierten, N-acylierten p-Aminophenole nicht beschrieben worden. Die bis jetzt bekannten Präparate zeigen neben einer geringen analgetischen Wirkung hauptsächlich antipyretische Eigenschaften.In the phenacetin series there are so far hydroxylated derivatives of the O-alkylated, N-acylated p-aminophenols are not has been described. The preparations known up to now show not only a low analgesic effect Mainly antipyretic properties.
Es wurde nun die bemerkenswerte Feststellung gemacht, daß durch Einführung von ίο einer oder mehreren Oxygruppen in das O-Alkylradikal der p-Acylaminophenole der Formel:The remarkable observation has now been made that by introducing ίο one or more oxy groups in the O-alkyl radical of the p-acylaminophenols of the formula:
Acyl·Acyl
C6H4-OR1 C 6 H 4 -OR 1
(R = H, Alkyl, Acyl, Aryl und Aralkyl;
R1= Oxalkyl)(R = H, alkyl, acyl, aryl and aralkyl;
R 1 = oxalkyl)
Körper mit vollständig anderer Wirkung entstehen. Die antipyretische Wirkung tritt nämlieh gegenüber der analgetischen in ganz auffallender Weise zurück. Außerdem wirken diese neuen Derivate des p-Aminophenols weniger hämoglobinbildend als Phenacetin. Sie haben daher ganz erhebliches medizinisches Interesse.Bodies emerge with a completely different effect. The antipyretic effect occurs compared to the analgesic in a very striking way. In addition, these new derivatives of p-aminophenol are less effective hemoglobin-forming as phenacetin. You therefore have very considerable medical issues Interest.
Die neuen Körper werden gewonnen durch Verätherung der p-Acylaminophenole mit mehrwertigen Alkoholen oder deren Anhydriden oder durch Umsetzung der p-Acylaminophenole mit den entsprechenden halogensubstituierten Alkoholen, wie Glykolchlorhydrin, Monochlorhydrin usw., oder durch Acylierung von den entsprechenden Oxyderivaten der O-alkylierten p-Aminophenole in der Aminogruppe.The new bodies are obtained by etherification of the p-acylaminophenols with polyhydric alcohols or their anhydrides or by reacting the p-acylaminophenols with the corresponding halogen-substituted alcohols, such as glycol chlorohydrin, monochlorohydrin, etc., or by acylation of the corresponding oxy derivatives of the O-alkylated p-aminophenols in the amino group.

Zu einer Lösung von 100 Teilen Acetyl-paminophenol in 300 Teilen Alkohol wird eine Lösung von 42 Teilen Ätzkali (85 prozentig) in 40 Teilen Wasser zugegeben. Man erhitzt diese alkoholische Lösung zum Sieden, fügt nach und nach 75 Teile a-Monochlorhydrin in 100 Teilen Alkohol hinzu und kocht noch einige Stunden am Rückflußkühler. Nach Absaugen des ausgeschiedenen Chlorkaliums und Abdampfen des Alkohols wird das Reaktionsprodukt aus Alkohol umkristallisiert. Man erhält so farblose Kristalle vom Schmelzpunkt 138 °, die in Wasser und Alkohol löslich sind.To a solution of 100 parts of acetyl-paminophenol in 300 parts of alcohol is a solution of 42 parts of caustic potash (85 percent) in 40 parts of water were added. This alcoholic solution is heated to the boil, after which and after 75 parts of a-monochlorohydrin in 100 parts Add alcohol and reflux for a few hours. After suctioning off the excreted Potassium chloride and evaporation of the alcohol, the reaction product is recrystallized from alcohol. Colorless crystals are obtained in this way with a melting point of 138 °, which are soluble in water and alcohol.
Zu einer Lösung von 150 Teilen Acetyl-paminophenol in 450 Teilen Alkohol wird eine Lösung von 63 Teilen Ätzkali (85 prozentig) in 60 Teilen Wasser hinzugegeben. Zur siedenden alkoholischen Flüssigkeit wird eine Lösung von 86 Teilen Glykolchlorhydrin in 150 Teilen Alkohol zugetropft und einige Stunden am Rückfiußkühler gekocht. Das ausgeschiedene Chlorkalium wird abgesaugt und der Alkohol ab-To a solution of 150 parts of acetyl-paminophenol in 450 parts of alcohol, a solution of 63 parts of caustic potash (85 percent) in 60 parts of water is added. To the boiling alcoholic liquid is a solution of 86 parts of glycol chlorohydrin in 150 parts of alcohol added dropwise and boiled for a few hours on the reflux condenser. The excreted potassium chloride is sucked off and the alcohol

Der hierbei erhaltene Acetylaminophenöläther ist in Wasser und Alkohol löslich und bildet farblose Kristalle vom Schmelzpunkt 120 °.steamed. The strongly colored reaction product can easily be recrystallized from alcohol. The acetylaminophen oil ether obtained in this way is soluble in water and alcohol and forms colorless crystals with a melting point of 120 °.
150 Teile Acetyl-p-aminophenol und 44 Teile Äthylenoxyd werden 10 Stunden im geschlossenen Rohr auf 150° erhitzt. Das Reaktionsprodukt wird aus Alkohol umkristallisiert und liefert den Acetyl-p-aminophenolglykoläther in Form farbloser Kristalle vom Schmelzpunkt 120150 parts of acetyl-p-aminophenol and 44 parts Ethylene oxide is heated to 150 ° in a closed tube for 10 hours. The reaction product is recrystallized from alcohol and supplies the acetyl-p-aminophenol glycol ether in Form of colorless crystals with a melting point of 120
100 Teile Acetyl-p-aminophenol, 200 Teile Glycerin und 100 Teile wasserfreies Natriumacetat werden 15 Stunden lang auf 200 bis 210 ° erhitzt. Der Rückstand wird mit Wasser ausgewaschen und aus Alkohol umkristallisiert. Man erhält so den Acetyl-p-aminophenolglycerinäther in Form farbloser Kristalle vom Schmelzpunkt 138 °.100 parts of acetyl-p-aminophenol, 200 parts of glycerin and 100 parts of anhydrous sodium acetate are heated to 200 to 210 ° for 15 hours. The residue is washed out with water and recrystallized from alcohol. Acetyl-p-aminophenol glycerol ether is obtained in this way in the form of colorless crystals with a melting point of 138 °.
200 Teile Acetyl-p-aminophenolglykoläther vom Schmelzpunkt 120° werden in einem Gemisch von 150 Teilen Pyridin und 5000 Teilen Aceton gelöst und zu der Lösung langsam unter Rühren 150 Teile Chlorameisensäureäthylester zugefügt. Nach beendeter Reaktion wird die Flüssigkeit mit Wasser verdünnt und das sich ausscheidende rohe Urethan des Acetyl-p-aminophenolglykoläthers aus Benzol umkristallisiert.
