Participants

Reaction Steps

A solution of dimethylsulfoxide (50 ml), water (5.0 ml), 2-chloro-1,4-diamino anthraquinone (5.0 g) and sodium hydroxide (1.0 g) is heated to 100° C. for 4 hours. The mixture is cooled and diluted with water until a precipitate forms. The precipitate is collected, washed, dried and recrystallized from carbon tetrachloride. The yield is 24 percent 2-(p-hydroxy ethyl phenoxy)-1,4-diamino anthraquinone with a melting point of 224° C. to 227° C.
