Reaction Steps
Dissolved 3-aminobenzonitrile (1.5 g, 12.7 mmol) in anhydrous dioxane (42 mL) under N2. Added phthalic anhydride (2.54 g, 17.1 mmol). Affixed Dean-Stark trap and refluxed for 16 h. Cooled to 0° C. and filtered off solid (2-((3-cyanophenyl)carbamoyl)benzoic acid). Concentrated filtrate to afford 3-(1,3-dioxoisoindolin-2-yl)benzonitrile (1.6 g) as a white solid. MS, calc'd=248.06. Obsv'd m/z: 248.91 (M+1).
