Reaction Steps

As shown in step 8-iv of Scheme 8, a solution of the above mixture (Compound 2029, 2.2 g, about 60% pure) in DMF (40 mL) at 0° C. was added dropwise over 2 hours to a suspension of 2-(4-amino-1H-pyrazol-1-yl)acetonitrile (844 mg, 6.9 mmol) and sodium carbonate (732 mg, 6.9 mmol) in DMF (20 mL). After addition was complete, the reaction mixture was stirred at 0° C. for 2 hours and heated at 80° C. for 15 hours. Additional sodium carbonate (732 mg) was added and the reaction mixture was heated at 90° C. for an additional 7 hours. After cooling, the mixture was poured into water and a precipitate formed. The solid was collected by filtration, washed with methyl t-butyl ether, and dried under high vacuum to provide 2-(4-(2-(5,6-dimethoxypyridin-3-yl)-5-oxo-5H-pyrrolo[3,4-b]pyridin-6(7H)-yl)-1H-pyrazol-1-yl)acetonitrile (Compound 25, 450 mg).
