Participants

Reaction Steps

The mixture of 4-(2,3-difluorobenzylamino)-6-(4-(piperidin-4-yl)phenylamino)nicotinamide (Example 209) (100 mg, 0.21 mmol), 3-pyridineboronic acid (265 mg, 2.10 mmol), Cu(OAc)2 powder (190 mg, 1.05 mmol) in 5 mL DCM and 1 mL pyridine was stirred at RT for 2 days. It was diluted with methanol and filtered through celite. The filtrate was treated with TFA and concentrated in vacuo. The residue was subjected to reverse phase HPLC to isolate the title compound. MS found for C29H28F2N6O as (M+H)+ 515.5. UV: λ=268 nm. 1H NMR: (CD3OD) δ 8.41 (1H, m), 8.16 (1H, s), 8.09 (1H, s), 8.06 (1H, s), 7.81 (1H, m), 7.35 (2H, dt, J=8.4; 2.0 Hz), 7.24 (1H, m), 7.16 (1H, m), 7.12-7.07 (3H, m), 5.79 (1H, s), 4.55 (2H, s), 4.12 (2H, m), 3.13 (2H, m), 2.91 (1H, m), 2.04 (2H, m), 1.87 (2H, m) ppm.
