Versuchsvorschrift
Methacrolein dimethylhydrazone (90 mg, 0.75 mmol) in one portion was added to a solution of 3-phenyl-5,8-dimethoxy-2-(1H)-quinolinone (190 mg, 0.71 mmol) in chloroform (50 ml.) The solution was agitated at room temperature for 3 hours and was evaporated. The residue was chromatographed over silica gel, eluting with ethyl acetate to give 120 mg (50%) of 6-methyl-3-phenyl-1H-1,8-diazaanthracen-2,9,10-trione (I-j). m.p. 275° C.
