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 (30 mg, 0.065 mmol), 4-chloro-5-fluoropyrimidine 196-2 (28 mg, 0.21 mmol) Pd(PPh3)4 (12 mg, 0.01 mmol) and K3PO4 (90 mg, 0.424 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-(5-fluoropyrimidin-4-yl)phenyl)acetamide 196. MS m/z 435.10 (M+1). 1H NMR 400 MHz (DMSO-d6) δ10.54 (s, 1H), 9.06 (d, 1H), 8.90 (d, 1H), 7.98 (m, 3H), 7.86 (d, 1H), 7.49 (d, 2H), 7.37 (m, 1H), 3.73 (s, 2H), 3.50 (m, 4H), 3.09 (t, 2H), 3.02 (t, 2H), 1.97 (s, 3H).
