반응 단계
A mixture of 2.74 g. of leuco-1,4,5,8-tetrahydroxyanthraquinone, 0.45 g. of ethylamine, a trace of sodium hydrosulfite and 60 ml. of aqueous methanol was stirred and warmed to 50° C. for one hour. To this was added 1.1 g. of dimethylaminopropylamine and the mixture was stirred and warmed at 50°-60° C. for 2 hours. Air was bubbled through this mixture while heating on a steambath for 6 hours. The mixture was cooled and the title product was collected.
