Procedure

To 3-(3,5-dichlorophenoxy)-4-(trifluoromethyl)pyridine-2(1H)-one (0.400 g, 1.23 mmol) and potassium carbonate (0.171 g, 1.23 mmol) suspended in dimethylformamide (5 mL) was added 3-(chloromethyl)-N,1-bis(4-methoxybenzyl)-1H-pyrazolo[3,4-b]pyridine-6-amine (0.522 g, 1.23 mmol) as a solution in dimethylformamide (2 mL). The reaction mixture was allowed to stir at room temperature. After 16 hours, the reaction mixture was diluted with water (50 mL) and extracted with ethyl acetate (2×100 mL). The combined organic extracts were washed with brine (3×100 mL), dried (MgSO4), filtered and the solvent was evaporated under reduced pressure to afford the title compound as a solid. 1H NMR (DMSO-d6) δ 7.90 (d, J=7.3 Hz, 1H), 7.75-7.67 (m, 1H), 7.52 (d, J=8.8 Hz, 1H), 7.34-7.30 (m, 1H), 7.27 (d, J=8.4 Hz, 2H), 7.13 (d, J=8.6 Hz, 2H), 7.07-7.03 (m, 2H), 6.83 (d, J=8.6 Hz, 2H), 6.77 (d, J=8.6 Hz, 2H), 6.59 (d, J=7.3 Hz, 1H), 6.40 (d, J=8.8 Hz, 1H), 5.31 (s, 2H), 5.29 (s, 2H), 4.48 (d, J=4.3 Hz, 2H), 3.71 (s, 3H), 3.69 (s, 3H). HRMS (M+1)=710.1557.
