Procedure
A mixture of N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acetamide 196-1 (20 mg, 0.04 mmol), 4-chloro-6-methylpyrimidine 198-1 (8 mg, 0.06 mmol) Pd(PPh3)4 (2 mg, 0.002 mmol) and K3PO4 (25 mg, 0.12 mmol) in dioaxane (0.6 mL) was flushed with nitrogen and heated to 110° C. for 2 hours. The salt was removed by filtration and the filtrate was taken to dryness by rotary evaporation. The residue was purified by reverse phase HPLC to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(4-(6-methylpyrimidin-4-yl)phenyl)acetamide 198. MS m/z 431.20 (M+1). 1H NMR 400 MHz (DMSO-d6) δ10.59 (s, 1H), 8.16 (d, 2H), 8.04 (d, 1H), 7.98 (s, 1H), 7.92 (m, 1H), 7.51 (d, 2H), 7.45-7.40 (m, 2H), 3.77 (s, 2H), 3.58 (b, 2H), 3.15 (b, 2H), 3.08 (b, 2H), 2.55 (s, 3H), 2.53 (s, 2H), 2.04 (s, 3H).
