A mixture of 50.6 g of 1-nitro-anthraquinone (99% pure) and 240 ml of o-xylene is reacted with 118 g of n-propylamine (molar ratio 10:1) at a temperature of 170° C. and under a pressure of 30 bars and for a reaction time of 80 minutes. Working up analogously to Example 1 gives 50 g (94% of theory) of 1-n-propylamino-anthraquinone, in which no further 1-nitro-anthraquinone can be detected.
