Synthesis of 3-Alkyl-5-arylamino-6,11-dihydro-3H-anthra[1,2-d][1,2,3]triazole-6,11-dione 2-Oxides by Nitrosation of 3-Alkylamino-5-arylamino-6H-anthra[1,9-cd]isoxazol-6-ones. -(GORNOSTAEV, L. M.; DOLGUSHINA, L. V.; TITOVA, N. G.; ARNOL'D, E. V.; LAVRIKOVA, T. I.; Russ.

Selective Alkamination of 3,5-Dihalogeno-6H-6-oxoanthra[1,9-cd]isoxazoles. -Title compounds (I) are converted into diamino derivatives by two subsequent reactions with aliphatic or alicyclic amines. The first substitution takes place at the 5-position at low temperatures, whereas the second amination at the 3-position requires a little more elevated temperatures. -(YUNOSOVA, O. N.; MITROKHIN, R.
