To a stirred mixture of compound (8) (200 mg, 0.502 mmol) and potassium carbonate (83 mg, 0.60 mmol) in DMF (2.0 mL) was added a solution of 4-(4-amino-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-fluorophenol (see Table 1, below) (148 mg, 0.602 mmol) in DMF (2.0 mL) and the reaction mixture stirred at RT for 18 hr. The solvent was removed in vacuo and the crude material was purified by flash column chromatography, eluting with 5% methanol in DCM, to afford the title compound, Intermediate D (81 mg, 27%) as a off-white solid: m/z 606/608 (M+H)+ (ES+) (Method B).
