Procedure

26.3 g of 1-nitro-anthraquinone (96%) is suspended in 110 g of formamide. If ammonia gas is introduced at 155° C, no more starting material may be detected by thin layer chromatography after 4 hours. After complete removal of the solvent by distillation under vacuum, 22.5 g of an 80% 1-amino-anthraquinone (80% of the theoretical yield) which contains 4%, by weight of 1-amino-anthraquinone imine are obtained.
