Reaction Conditions

Reaction Steps

Pre-formed catalyst (0.05 mL, from Example 40) was added to a mixture 1-{1-[5-chloro-2-methoxy-4-methyl-3-(1-methyl-1H-pyrazol-4-yl)phenyl]ethyl}-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (7.7 mg, 0.019 mmol), zinc (0.54 mg, 0.0082 mmol) and zinc cyanide (2.2 mg, 0.019 mmol) in N,N-dimethylacetamide (0.3 mL). The mixture was degassed with nitrogen 3 times. The reaction was heated at 120° C. for 1.5 h. The crude was purified using 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 (2.1 mg, 27%). The product was isolated as a single enantiomer. LCMS calculated for C21H23N8O (M+H)+: m/z=403.2; Found: 403.2.
