Reaction Steps

63.3 g of 1-nitroanthraquinone (99% pure) in 320 ml of cyclohexane are reacted with 147.8 g of isopropylamine (molar ratio 10:1) for 70 minutes at a temperature of 160° C. and under a pressure of 50 bars. Working up analogously to Example 1 gives 62 g (94.5% of theory) of 97.6% pure 1-isopropylamino-anthraquinone.
