Procedimiento

Methyl 2-bromo-2-methylpropanoate (663 mL, 5.13 mmol) was added to 2-chloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidine (358.1 g, 1.28 mol) (see Preparation 40), potassium iodide (21.3 g, 128 mmol) and cesium carbonate (1670 g, 5.13 mol) in DMF (7162 mL). The mixture was heated at 60° C. for 19 hours. The reaction mixture was diluted with water (7000 mL) and stirred at room temperature for 42 hours. The mixture was filtered and the solid was washed with water (500 mL) to afford the title compound as a beige solid in 92% yield, 445.8 g.
