실험 절차
To (3S,6R)-1-[6-(4-cyano-3-fluorophenyl)-2-(methylamino)-4-pyrimidinyl]-N-cyclohexyl-6-methyl-3-piperidinecarboxamide (260 mg, 0.58 mmol) in EtOH (10 mL) as a suspension at room temperature in a microwave vial was added hydrazine monohydrate (807 uL, 16.7 mmol, 30 equiv) in one portion. The mixture was capped and heated at 100° C. for 48 hours. A duplicate run was performed. The crude reactions from both runs were combined, and concentrated in vacuo. The residue was taken up in 10 mL of water. The resulting suspension was sonicated briefly, and filtered. The solids collected were dried under vacuum at room temperature over P2O5 for 18 hours, and then at 65° C. under vacuum for another 18 hours to afford the title compound (410 mg) as a cream-colored solid. LC-MS (ES) m/z=463 [M+H]+. 1H NMR (400 MHz, CD3OD): δ 1.16-1.32 (m, 3H), 1.29 (d, J=6.8 Hz, 3H), 1.34-1.45 (m, 2H), 1.65-1.68 (m, 1H), 1.76-1.81 (m, 5H), 1.85-1.92 (m, 2H), 1.97-2.05 (m, 1H), 2.35-2.42 (m, 1H), 2.97 (s, 3H), 3.11-3.15 (m, 1H), 3.64-3.70 (m, 1H), 4.45-4.65 (bs, 1H), 4.72-4.92 (bs, 1H), 6.45 (s, 1H), 7.52 (dd, J=8.5, 1.14 Hz, 1H), 7.75 (d, J=8.3 Hz, 1H), 7.85 (s, 1H).
