Procedure

A mixture of 5-(3-fluoro-4-hydroxyphenyl)-3-methyl-2-(phenylamino)pyrimidin-4(3H)-one (0.009 g, 0.03 mmol, prepared in Example 45, step F), 4-chloro-3-iodo-1-(4-methoxybenzyl)-1H-pyrazolo[3,4-b]pyridine (0.010 g, 0.0250 mmol) and DMAP (0.006 g, 0.05 mmol) in bromobenzene (0.300 mL) under N2 was stirred at 150° C. for 3 days. The reaction was concentrated in vacuo to remove as much bromobenzene as possible and then purified directly by flash column chromatography, eluting with 10:1 CH2Cl2/MeOH. The desired product (0.013 g, 76%) was obtained as a yellow solid. LRMS (APCI pos) m/e 675 (M+1).
