実験手順

TFA (0.3 mL, 4.03 mmol) was added to a solution of 1-(3-(1H-benzo[d]imidazol-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)-3-cyclopentylurea (6 mg, 0.013 mmol) in CH2Cl2 (4 mL). The reaction mixture was stirred at room temperature for 24 h, and then the solvent was removed in vacuo. Purification by flash chromatography (6% CH3OH/CH2Cl2) afforded the title compound (4 mg) as an off-white solid. 1H NMR (400 MHz, CD3OD): δ 8.36 (s, 1H), 7.81 (m, 2H), 7.60 (d, 1H, J=8.8 Hz), 7.46 (m, 3H), 4.11 (t, 1H, J=6.4 Hz), 2.00 (m, 2H), 1.75 (m, 2H), 1.65 (m, 2H), 1.51 (m, 2H); ESI-MS [M+H]+: 361.3.
