Reaction Steps

A mixture of 1-(4-methoxybenzyl)-4-chloro-3-iodo-1H-pyrazolo[3,4-b]pyridine (7.00 g, 17.52 mmol, obtained from Example 84, Step D), cesium acetate (33.62 g, 175.2 mmol) and DMF (175 mL) was heated to 100° C. for 12 hours. The reaction was cooled to room temperature, diluted with water (50 mL), extracted with EtOAc (100 mL), dried over sodium sulfate, filtered and concentrated. The residue was purified by flash column chromatography (5% MeOH in CH2Cl2) to afford the product (2.23 g, 79% yield) as a light orange solid. LRMS (APCI pos) m/e 381.9 (M+H).
