Reaction Steps

A mixture of 6-chloro-2-(4-(4-methylpiperazin-1-yl)phenylamino)nicotinamide (60 mg, 0.173 mmol), (R)-1-(4-methylthiazol-2-yl)-3-(piperidin-3-yl)urea hydrochloride (96 mg, 0.347 mmol), and DIEA (0.182 mL, 1.041 mmol) in N-methyl-2-pyrrolidinone (2 mL) was heated at 120° C. overnight. The reaction mixture was quenched with water, resulting in the formation of light brown precipitate. The solid was filtered, washed with water, and dried under vacuum. The residue was purified by MPLC chromatography (ISCO, 7% NH4OH/MeOH/CH2Cl2, 40 g silica gel column) to give 22 mg of (R)-2-(4-(4-methylpiperazin-1-yl)phenylamino)-6-(3-(3-(4-methylthiazol-2-yl)ureido)piperidin-1-yl)nicotinamide as a yellow solid. LCMS: (M+H)+=550.08; 1H NMR (400 MHz, CDCl3) δ ppm 10.62 (1H, s), 7.47 (2H, d, J=9.23 Hz), 7.33 (1H, d, J=8.79 Hz), 6.85 (2H, d, J=9.23 Hz), 6.28 (1H, s), 5.91 (1H, d, J=8.79 Hz), 5.69 (2H, br. s.), 4.00 (1H, d, J=7.47 Hz), 3.65-3.79 (2H, m), 3.55-3.64 (1H, m), 3.40-3.50 (1H, m), 3.07-3.14 (4H, m), 2.52-2.58 (4H, m), 2.33 (3H, s), 2.19 (3H, s), 1.87-1.98 (1H, m), 1.55-1.82 (3H, m).
