Reaction Steps

2-(1H-Pyrrolo[2,3-b]pyridin-6-yl)-isoindole-1,3-dione (179 mg, 0.68 mmol) was suspended in acetonitrile (3.4 mL). Iodomethane (53 μL, 0.843 mmol) and cesium carbonate (443 mg, 1.36 mmol) were then added. After 16 h, water was added and the aqueous layer was extracted with ethyl acetate. The combined organic extracts were dried (sodium sulfate), filtered and concentrated in vacuo to give 2-(1-methyl-1H-pyrrolo[2,3-b]pyridin-6-yl)-isoindole-1,3-dione (0.22 g, 117%) as a light brown solid, which was used directly in the next step without further purification. LCMS (EI/CI) m/z: 278 [M+H].
