Beispiel 5 : 10 kg fein verteiltes Bromanthrapyridon (s. Patent Nr. 33991, Beispiel 1) werden mit 200 kg 20prozentigem Ammoniak in einem mit Rührwerk versehenen Autoklaven auf 1500 erhitzt, bis in einer abfiltrierten und ausgewaschenen Probe kein Brom mehr nachzuweisen ist. Man saugt ab, wäscht aus und krystallisiert nach dem Trocknen aus Nitrobenzol um. Man er-

Example 5: 10 kg of finely divided bromanthrapyridone (see Patent No. 33991, Example 1) are heated to 1500 with 200 kg of 20 percent ammonia in an autoclave equipped with a stirrer until no more bromine can be detected in a filtered and washed sample. It is filtered off with suction, washed out and, after drying, crystallized from nitrobenzene. Man

in concentrated sulfuric acid with the addition of boric acid is yellow with intensely green fluorescence. The body is identical to the aminoanthrapyridone also obtainable from 1-acetylmethylamino-4-aminoanthrachione by the process of patent no. 33991.
Example 6: 10 kg of p-bromoauthrapyridone (see patent no. 33991, example 1) are in 500 kg
