Reaction Steps

4,5-dimethylphthalic anhydride (1.7 g, 9.6 mmol) and 4-fluoroaniline (1.1 g, 9.6 mmol) were stirred with heating in dimethylformamide at 150° C. for 1 hr. After cooling, water was added to the reaction mixture, and the precipitated crystals were collected by filtration, washed with water, and dried. The resulting crystals were purified by silica gel chromatography (chloroform) to give 2.0 g of 5,6-dimethyl-2-(4-fluorophenyl)isoindolin-1,3-dione.
