Reaction Steps

A solution of 6-chloro-5-fluoro-2-(4-fluorophenylamino)nicotinamide (50 mg, 0.176 mmol) and piperidine (1 mL, 10.12 mmol) was sealed in a small microwave vial and heated in a heating block at 100° C. for 2 hrs. The reaction mixture was diluted with CH2Cl2 and washed with bicarbonate and water. The reaction mixture was concentrated and the dark crude material was chromatographed (ISCO Companion 40 g silica gel column and eluted with (90:9:1 CH2Cl2:MeOH: NH4OH)t/CH2Cl2 gradient (20-100%)) to give 50 mg of 5-fluoro-2-(4-fluorophenylamino)-6-(piperidin-1-yl)nicotinamide as a brown solid. LCMS: (M+H)+=333.21. 1H NMR (400 MHz, CDCl3) δ ppm 10.68 (1H, s), 7.52-7.57 (2 H, m), 7.22 (1H, d, J=14.06 Hz), 6.94-7.00 (2H, m), 5.47 (2H, br. s.), 3.64 (4H, d, J=6.15 Hz), 1.62-1.72 (6H, m).
