Procedure

A suspension of 4-(1-(4-methoxybenzyl)-3-iodo-1H-pyrazolo[3,4-b]pyridin-4-yloxy)-3-fluorobenzenamine (100 mg, 0.204 mmol, obtained from Example 7, Step B), 3-aminocyclohexanol (70.5 mg, 0.612 mmol), Cu(I)I (7.77 mg, 0.0408 mmol), K2CO3 (141 mg, 1.02 mmol) and L-proline (9.39 mg, 0.082 mmol) was stirred in DMSO (5 mL) and heated to 100° C. for 12 hours. Water (5 mL) was added and the reaction mixture was extracted with CH2Cl2. The organic layer washed with water and brine, dried with Na2SO4, filtered and concentrated. The residue was purified by flash column chromatography (5% MeOH in CH2Cl2) to afford the product (47 mg, 48.3% yield) as a brown oil. LRMS (APCI pos) m/e 694.2 (M+H).
