Reaction Steps

The use of polar solvents as reaction media results in only very poor yields and lengthy reaction times are required. For example, the reaction of 1-nitroanthraquinone with a 300% excess of isopropylamine at 75° C after 100 hours gives a yield of only 70% of 1-isopropylaminoanthraquinone.
