Reaction Steps

The above catalyst (0.05 mL) was added to a mixture of 4-{3-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5-chloro-2-methoxy-6-methylphenyl}-N-(2-hydroxyethyl)-N-methylpyridine-2-carboxamide (from Example 19) (4.0 mg, 0.0078 mmol), zinc (0.22 mg, 0.0034 mmol) and zinc cyanide (0.92 mg, 0.0078 mmol) in N,N-dimethylacetamide (0.1 mL). The mixture was degassed and then the reaction was heated at 120° C. for 1.5 hours. The crude mixture was applied on RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 30 mL/min) to give the desired product. The product was isolated as a racemic mixture. LCMS calculated for C26H29N8O3 (M+H)+: m/z=501.2; Found: 501.2
