Procedure

A mixture of 6-chloro-5-fluoro-2-(4-(4-methylpiperazin-1-yl)phenylamino)nicotinamide (70 mg, 0.192 mmol), pyridin-4-ylboronic acid (23.65 mg, 0.192 mmol), K2CO3 (53.2 mg, 0.385 mmol) and Pd(Ph3P)4 (11.12 mg, 9.62 μmol) in THF (1 mL) was heated at 90° C. overnight in a sealed vial. The reaction mixture was extracted between saturated NaHCO3 and methylene chloride, concentrated and the residue was purified by prep-HPLC. The product containing fractions were collected, basified with 1N NaOH, extracted with methylene chloride, concentrated to give 26 mg of product as orange-red solid. LC-MS: (M+H)+=407.11. 1H NMR (400 MHz, chloroform-d-MIX) δ ppm 8.55-8.60 (2H, m), 7.91 (2H, d, J=5.71 Hz), 7.76 (1H, d, J=11.42 Hz), 7.52 (2H, d, J=9.23 Hz), 6.89 (2H, d, J=8.79 Hz), 3.08-3.16 (4H, m), 2.51-2.60 (4H, m), 2.29 (3H, s).
