Participants

Reaction Steps

A suspension of 3.11 g. of 1,4-dihydroxy-5,8-bis[[2-(2-hydroxyethylamino)ethyl]amino]anthraquinone [prepared as described in Example 1(A)] in 150 ml. of acetone is stirred and heated under rapid reflux. The condensate is returned to the flask by percolation through a dehydration system consisting of 40 g. of 4 A molecular sieves supported by a sintered glass plate. After a 24 hour reaction period the resulting solid is collected by filtration and is washed with hot acetone to give 2.77 g. of the product of the Example as a blue-black solid, m.p. 255°-256° C.
