Reaktionsschritte

A slurry of N1-(4-methoxybenzoyl)-1,2-benzenediamine (100 mg, 0.413 mmol) and 4-tert-butylphthalic anhydride (84.3 mg, 0.413 mmol) in toluene (1.5 mL) was placed in a bath heated to 110° C. After 16 h, the mixture was concentrated in vacuo and the residue purified by flash chromatography (silica gel, hexanes/ethyl acetate) to afford 149 mg (85%) of the title compound. The material was further purified by recrystallization from hexanes/ethyl acetate.
