Description
Verfahren zur Darstellung eines Emwandlungsproduktes der per!-Cyaainaphthalin sulfosäure. Vorliegendes Patent bezieht sich auf die Darstellung von 6-Xethoxynaphthostyril, da durch gekennzeichnet, dass man 6-Oxynapli- thostyril mit methylierenden Mitteln behan delt.
Das so erhaltene neue 6-Methoxynaphtho- styril ist ein fast farbloses Pulver, das:, <B>i</B> aus Benzol umkristallisiert, bei 223 schmilzt. In konzentrierter Schwefelsäure ist es mit schwach grünlicher Farbe löslich und wird durch Erwärmen mit verdünnten Alkalilaugen zur 6-Methoxy-l-aminonaph- thalin-8-earbonsäure verseift.
<I>Beispiel:</I> 1. Teil des Natriumsalzes von 6-Oxy- naphthostyril (vergleiche Patent Nr. 128898) wird mit 4 Teilen p-Toluolsulfosä.uremethyl- ester, -1 Teilen Soda und etwa 80 Teilen Trichlorbenzol auf etwa 160 bis 170 erhitzt, bis eine Probe nicht mehr mit Dia.zoverbin- Jungen kuppelt. Das Trichlorbenzol wird mit Wasserdampf abgetrieben und der Rückstand filtriert, gewaschen und getrocknet.
Process for the preparation of a conversion product of per-cyaainaphthalene sulfonic acid. The present patent relates to the preparation of 6-xethoxynaphthostyril, characterized in that 6-oxynaplothostyril is treated with methylating agents.
The new 6-methoxynaphthostyril obtained in this way is an almost colorless powder which:, <B> i </B>, recrystallizes from benzene, melts at 223. It is soluble in concentrated sulfuric acid with a pale greenish color and is saponified to 6-methoxy-1-aminonaphthalene-8-carboxylic acid by heating with dilute alkali lye.
<I> Example: </I> 1. Part of the sodium salt of 6-oxynaphthostyril (see patent no. 128898) is mixed with 4 parts of p-toluenesulfosate, -1 part of soda and about 80 parts of trichlorobenzene to approx 160 to 170 heated until a sample no longer couples with Dia.zoverbin boys. The trichlorobenzene is driven off with steam and the residue is filtered, washed and dried.
