Description
10-15 мин. Реакционную массу выдерживают при нагревании 8 ч и после охлаждени отфильтровывают. Осадок промывают водой и обрабатывают 3%-ным раствором сол ной кислоты, отфильтровывают и из фильтрата подщелачиванием выдел ют 1-амино-6-нитрокарбазол , который кристаллизуют из 30%-него этанола, выход 53%, т. пл. 267°С.10-15 min. The reaction mass is maintained at heating for 8 h and after cooling is filtered. The precipitate is washed with water and treated with 3% hydrochloric acid solution, filtered and 1-amino-6-nitrocarbazole is separated from the filtrate by alkalisation, which crystallizes from 30% ethanol, yield 53%, m.p. 267 ° C.
