Reaction Steps

In a 40 mL sealed vial was added (R)-benzyl 1-(4-(5-fluoro-6-phenylpicolinamido)-1-methyl-1H-pyrazol-5-yl)azepan-4-ylcarbamate (62 mg, 0.11 mmol), 1,4-cyclohexadiene (0.11 mL, 1.14 mmol) and ethanol (7 mL). 10% Pd/C (18.2 mg, 0.017 mmol) was added and the reaction vial was vacuum purged with nitrogen three times. The reaction mixture was then stirred at 95° C. under nitrogen for 2 h. After cooling down to room temperature, the reaction mixture was filtered through Celite and rinsed thoroughly with methanol. The solvent was distilled off under reduced pressure to give the crude product which was purified via reverse phase HPLC to afford 229. 1H NMR (400 MHz, DMSO) δ 8.40 (s, 1H), 8.18-7.98 (m, 4H), 7.68-7.48 (m, 3H), 3.68 (s, 3H), 3.25-3.03 (m, 5H), 2.02-1.75 (m, 3H), 1.74-1.51 (m, 3H). MS (ESI) m/z: 409.2 [M+H+].
