Procedure

Into a microwave tube, (3S)-1-[2-amino-6-(4-cyano-3-fluorophenyl)-4-pyrimidinyl]-N-(3-fluorophenyl)-3-piperidinecarboxamide (90 mg, 0.207 mmol), 3 mL of EtOH, Hunig's base (0.109 mL, 0.621 mmol), and hydrazine anhydrous (0.026 mL, 0.829 mmol) were added, and the yellow mixture was heated at 150° C. for 150 minutes under microwave conditions. The solution turned into 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 purified by HPLC (CH3CN/H2O w/0.1% HCO2H) to afford a formic acid salt of the title compound (65 mg) as a light yellow solid. LC-MS (ES) m/z=447 [M+H]+. 1H NMR (400 MHz, CD3OD): δ 1.35-1.44 (m, 1H), 1.69 (m, 1H), 1.91-2.11 (m, 2H), 2.12-2.27 (m, 1H), 2.61-2.78 (m, 1H), 3.39-3.80 (m, 1H), 4.24-4.41 (m, 1H), 4.68-5.17 (m, 1H), 6.85 (m, 2H), 7.22-7.47 (m, 3H), 7.51-7.60 (m, 1H), 7.79 (m, 1H), 7.89-8.01 (m, 1H).
