Reaction Steps

To a mixture of tert-butyl 3-(2-(1,3-dioxoisoindolin-2-yl)ethyl)-2-oxoindoline-1-carboxylate (1.00 g, 2.46 mmol) and potassium carbonate (679 mg, 4.92 mmol) in DMF (5 mL) was added iodomethane (524 mg, 3.69 mmol) at ˜0° C. to 5° C. The resulting reaction mixture was stirred at room temperature for 16 h. The resulting mixture was treated with water and extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated to give a crude product, which was purified by silica gel column chromatography (10-25% ethyl acetate in petroleum ether to afford the title compound (700 mg, 1.66 mmol, 67% yield) as a brown solid. MS (ESI) m/z 421.1 [M+H]+.
