Reaction Steps

CeCl3 (0.1 mmol) as a catalyst and 4 equivalents of 4-chloroaniline (10 mmol) were added to 6,7-dibromo-5,8-quinolindion (10 mmol) dissolved in ethanol (100 ml). The reaction mixture was heated at reflux for 8 hrs. After reading the completion of reaction by TLC, it was cooled, filtered, and recrystallized with ethanol to give redish powder of 6-[(N-4-chlorophenyl)amino]-7-bromo-5,8-quinolidione.
