Procedure

To 3-chloro-5-{[2-oxo-4-(trifluoromethyl)-1,2-dihydropyridin-3-yl]oxy}benzonitrile (3C, 0.150 g, 0.477 mmol) and potassium carbonate (0.066 g, 0.477 mmol) suspended in dimethylformamide (1 mL) was added 3-(chloromethyl)-N,1-bis(4-methoxybenzyl)-1H-pyrazolo[3,4-b]pyridin-6-amine (0.202 g, 0.477 mmol) as a solution in dimethyl formamide (1 mL). The reaction mixture was allowed to stir at room temperature. After 16 hours, the reaction mixture was diluted with ethyl acetate (50 mL), washed with brine (3×25 mL), dried (MgSO4), filtered and the solvent was evaporated under reduced pressure. The resulting residue was adsorbed onto silica gel and purified by column chromatography on a pre-packed silica gel Redi Sep 40 gram column, eluting with 0-5% methanol in CH2Cl2 to afford the title compound. 1H NMR (DMSO-d6) δ 7.91 (d, J=7.0 Hz, 1H), 7.76-7.74 (m, 1H), 7.72-7.68 (m, 1H), 7.58-7.56 (m, 1H), 7.54 (d, J=8.6 Hz, 1H), 7.49-7.47 (m, 1H), 7.26 (d, J=8.6 Hz, 2H), 7.13 (d, J=8.6 Hz, 2H), 6.83 (d, J=8.6 Hz, 2H), 6.76 (d, J=8.6 Hz, 2H), 6.59 (d, J=7.2 Hz, 1H), 6.40 (d, J=8.9 Hz, 1H), 5.30 (s, 2H), 5.28 (s, 2H), 4.50-4.46 (m, 2H), 3.71 (s, 3H), 3.69 (s, 3H). LRMS (M+1)=700.6.
