Reaction Steps
A mixture of 1-chloro-3H-dibenz[f,ij]isoquinoline-2,7-dione (1.8 g), ethanolamine (14 ml), sodium acetate (1 g), and a trace of cupric acetate was heated at 100°-110° C. until reaction appeared to be complete (~1 hr). After cooling, methanol (10 ml) was added to the reaction mixture at about 80° C. Upon further cooling the product crystallized in the form of yellow solid. After being isolated by filtration and recrystallized from methyl Cellosolve, the product melted at 203°-206° C. and had an absorption maxium at 441 nm in the visible spectrum in acetone solution, thus imparting a greenish-yellow color thereto. The structure is as follows: ##STR5##
