Reaction Steps

Into a microwave tube, (3S)-1-[2-amino-6-(4-cyano-3-fluorophenyl)-4-pyrimidinyl]-N-(phenylmethyl)-3-piperidinecarboxamide (190 mg, 0.441 mmol), 3 mL of EtOH, Hunig's base (0.308 ml, 1.761 mmol), and hydrazine anhydrous (0.083 ml, 2.64 mmol) were added, and the yellow mixture was heated at 150° C. for 180 minutes under microwave conditions. 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, and EtOAc was used to triturate, affording the title compound (29 mg) as a light yellow solid. LC-MS (ES) m/z=443 [M+H]+. 1H NMR (400 MHz, DMSO-d6): δ 1.31-1.52 (m, 1H), 1.61-1.81 (m, 2H), 1.86-2.04 (m, 1H), 2.29-2.45 (m, 1H), 2.77-3.05 (m, 2H), 4.17-4.25 (m, 1H), 4.31-4.69 (m, 3H), 5.38 (s, 2H), 6.09 (s, 2H), 6.58-6.70 (m, 1H), 7.17-7.39 (m, 5H), 7.58 (dd, J=8.6, 1.3 Hz, 1H), 7.70 (d, J=8.6 Hz, 1H), 7.96 (s, 1H), 8.46 (t, J=5.9 Hz, 1H), 11.50 (s, 1H).
