Reaction Steps

A flask is charged with 3-amino-5-bromo pyridine (1.00 g, 5.78 mmol), phthalic anhydride (0.856 g, 5.78 mmol) and acetic acid (20 mL). The reaction is refluxed overnight. The reaction is then cooled to room temperature and concentrated in vacuo. The crude is dissolved in ethyl acetate and washed with water once. The organic layer is dried over sodium sulfate and concentrated in vacuo to afford 2-(5-bromo-pyridin-3-yl)-isoindole-1,3-dione. MS (ESI) m/z 305.1 (M+H)+
