A solution of 6-chloro-2-(4-(morpholine-4-carbonyl)phenylamino)nicotinamide (100 mg, 0.277 mmol) and piperazine (477 mg, 5.54 mmol) in NMP (2 mL) was heated to 120° C. overnight. The reaction mixture was diluted with CH2Cl2, washed with satd NaHCO3, separated, and concentrated. The residue was purified by MPLC chromatography (ISCO, 8% NH4OH/MeOH/CH2Cl2, 40 g silica gel column) to give 72 mg of 2-(4-(morpholine-4-carbonyl)phenylamino)-6-(piperazin-1-yl)nicotinamide as a white solid. LCMS: (M+H)+=411.35. 1H NMR (400 MHz, CDCl3) δ ppm 11.20 (1H, s), 7.70 (2H, d, J=8.56 Hz), 7.54 (1H, d, J=9.06 Hz), 7.38 (2H, d, J=8.56 Hz), 6.04 (1H, d, J=8.81 Hz), 5.58 (2H, s), 3.58-3.78 (12H, m), 2.92-3.01 (4H, m).
