Reaction Steps

A suspension of 9,10-dibromo-1,6,7,12-tetrachloroperylene-3,4-dicarboxylic acid anhidride (1.24 g, 2.0 mmol), diphenylamine (0.40 g, 2.40 mmol), Pd(AcO)2 (10 mmol %), sodium-tert-butoxide (0.48 g, 5.0 mmol), tricyclohexylphosphine (20 mol %) in 70 ml toluene was stirred at 100° C. under argon atmosphere for 24 h. The solvent was removed under reduced pressure. The solid was dissolved in dichloromethane and acetic acid and stirred overnight at 70° C. The solvent was removed under reduced pressure. The crude product was purified by column chromatography using dichloromethane as eluent on silica. Yield 0.50 g (40%).
