Verfahren zur Darstellung von Anthrachinonoxazolen. Patentiert im Deutschen Reiche vom 28. Oktober 1913 ab. Process for the preparation of anthraquinone oxazoles. Patented in the German Empire on October 28, 1913.
In der Patentschrift 236857, Kl. 22 b, ist angegeben, daß beim Erhitzen von Benzoylamino-o-halogenanthrachinonen mit kondensierenden Mitteln Phenanthridonderivate entstehen, indem eine Halogenwasserstoffabspaltung zwischen dem Halogen des Anthrachinonrestes und einem orthoständigen Η-Atom der Benzoylgruppe stattfindet. Diese angeblichen Phenanthridonderivate wurden durch die Untersuchungen von P. Nawiasky (Zeitschrift für ang. Chemie 26, Seite 438) und von Fr. Ulimann und W. Junghanns (Ann. 399, Seite 331 und 335) als Anthrachinon-pphenyloxazole charakterisiert.In the patent specification 236857, class 22 b, it is indicated that when heating benzoylamino-o-halogenanthraquinones with condensing agents phenanthridone derivatives are formed by splitting off hydrogen halide between the halogen of the anthraquinone residue and an ortho Η atom of the Benzoyl group takes place. These alleged phenanthridone derivatives were identified by the investigations by P. Nawiasky (Zeitschrift für ang. Chemie 26, page 438) and by Fr. Ulimann and W. Junghanns (Ann. 399, pages 331 and 335) as anthraquinone-pphenyloxazole characterized.
Es wurde nun gefunden, daß eine innere Kondensation ebenfalls stattfindet, wenn man Benzoylamino-o-nitroanthrachinone mit kondensierenden Mitteln behandelt, und daß auch die so erhältlichen Derivate Oxazole sind.It has now been found that internal condensation also takes place when one Benzoylamino-o-nitroanthraquinones treated with condensing agents, and that too the derivatives obtainable in this way are oxazoles.

CSH,C S H,
Die Verwendbarkeit der Benzoylamino-onitroänthrachinone zu diesem Zweck ist durchaus überraschend, da Halogen- und Nitroderivate auch in der Anthrachinonreihe in ihren Reaktionen nicht allgemein übereinstimmen und insbesondere Anthrachinonderivate, die eine Nitrogruppe in 2-Stellung enthalten, sonst recht beständig sind. Somit war eine glatte Bildung von Oxazolen unter Abspaltung von salpetriger Säure beim vorliegenden Verfahren nicht von vornherein zu erwarten.The usability of the benzoylamino-onitroanthraquinones for this purpose it is quite surprising that halogen and nitro derivatives are also in their anthraquinone series Reactions do not generally match, and in particular anthraquinone derivatives that contain a nitro group in the 2-position, are otherwise quite stable. Thus it was a smooth one Formation of oxazoles with elimination of nitrous acid in the present process not to be expected in advance.
' 2 Teile des in der Patentschrift 254185 beschriebenen 2-Nitro-i · 4-dibenzoylaminoanthrachinons werden mit 2 Teilen calc. Soda und 10 Teilen Naphtalin etwa 1 Stunde am Rückflußkühler erhitzt. Das nach dem Entfernen des Naphtalins mittels Alkohols und dem Auswaschen mit Wasser erhaltene Reaktionsprodukt ist reines 4-Benzoylamino-i · 2-anthrachinonju-pheriyloxazol. '2 parts of that described in patent specification 254185 2-Nitro-i · 4-dibenzoylaminoanthraquinones are calc with 2 parts. Soda and 10 parts of naphthalene refluxed for about 1 hour. That after removal of the naphthalene obtained by means of alcohol and washing with water is pure 4-benzoylamino-i · 2-anthraquinoneju-pheriyloxazole.
Aus Chlorbenzol kristallisiert es in schönen orangefarbenen, bei 298 ° schmelzenden Nadeln. Der Körper ist ziemlich schwer in den gewöhnlichen Lösungsmitteln mit oranger Farbe löslich. Mit konzentrierter Schwefelsäure gibt er eine braunorange Lösung, die beim Erhitzen fast farblos wird, indem die Benzoylgruppe abgespalten wird. Das so erhaltene Aminoderivat kristallisiert aus Nitrobenzol in dunkelvioletten, bei 360 ° schmelzenden Nadeln.It crystallizes from chlorobenzene in beautiful orange needles that melt at 298 °. The body is quite heavy in the common solvents with an orange color soluble. With concentrated sulfuric acid he gives a brown-orange solution, which when heated becomes almost colorless as the benzoyl group is split off. The thus obtained Amino derivative crystallizes from nitrobenzene in dark purple needles that melt at 360 °.
