Reaction Steps

4-(6-Amino-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-bromo-6-fluoro-phenol hydrobromide (Example 42a) (0.07 g, 0.167 mmol), Zn(CN)2 (0.020 g, 0.167 mmol), Pd2(dba)3 (0.076 g, 0.08 mmol) and DPPF (0.092 g, 0.167 mmol) are dissolved in DMF (2.5 ml) and heated to 180° C. for 40 minutes. The reaction mixture is flitered through Celite® (filter agent) washing with MeOH, the filtrate is concentrated in vacuo and purification of the resulting residue is by preparative HPLC (water/acetonitrile, 0.1% TFA) affords the title compound as a white solid.
