Reaction Steps
2-(methoxypropylamino)-1,4-dihydroxyanthraquinone was prepared as follows: 60 grams of 1,4-dihydroxyanthraquinone, 15.5 grams of boric acid, and 89 grams of methoxypropylamine were slurried in 125 ml of water. The slurry was stirred and heated to 65° Celsius, and a strong stream of air was bubbled through it. These conditions were maintained about nine hours, or until thin layer chromatography of the reaction mixture failed to isolate any, 1,4-dihydroxyanthraquinone.
