Reaction Steps

Into a microwave tube, (3S)-1-[2-amino-6-(4-cyano-3-fluorophenyl)-4-pyrimidinyl]-N-[4-(methyloxy)phenyl]-3-piperidinecarboxamide (190 mg, 0.426 mmol), 3 mL of EtOH, Hunig's base (0.223 mL, 1.28 mmol), and hydrazine anhydrous (0.053 ml, 1.702 mmol) were added, and the yellow mixture was heated to 150° C. for 180 minutes in microwave. The solution turned black. LCMS showed mainly product. The black solids were filtered and the yellow filtrate was evaporated. The resulting yellow residue was dissolved in CH3OH at 50° C., and EtOAc was used to triturate. When the solution turned slightly cloudy, it was cooled to room temperature to get pure crystallized light yellow title compound (22 mg). LC-MS (ES) m/z=459 [M+H]+. 1H NMR (400 MHz, DMSO-d6): δ 1.46 (m, 1H), 1.65-1.84 (m, 2H), 1.98 (m, 1H), 2.79-3.06 (m, 2H), 3.72 (s, 3H), 4.49 (m, 1H), 4.68 (m, 1H), 5.37 (s, 2H), 6.10 (s, 2H), 6.68 (s, 1H), 6.88 (d, J=9.1 Hz, 2H), 7.53 (d, J=9.1 Hz, 2H), 7.58-7.65 (m, 1H), 7.66-7.78 (m, 1H), 7.97 (s, 1H), 9.87 (s, 1H), 11.49 (s, 1H).
