3-Fluorobenzoic acid (10 mg, 0.029 mmol), HOBt (6 mg, 0.044 mmol), EDC (9 mg, 0.045 mmol) and sodium bicarbonate (2.5 mg, 0.029 mmol) were added to a solution of 3-(1H-benzo[d]imidazol-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-amine (10 mg, 0.029 mmol) in DMF (6 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 (8 mg) as a off white solid. 1H NMR (400 MHz, CDCl3): δ 8.40 (d, 1H, J=1.6 Hz), 8.15-8.13 (m, 2H), 7.95 (s, 1H), 7.58 (m, 2H), 7.52 (d, 1H, J=9.6 Hz), 7.42-7.36 (m, 2H), 7.21 (m, 2H), 5.69 (dd, 1H, J=2.4 and 9.2 Hz), 3.99 (m, 1H), 3.72 (m, 1H), 2.55 (m, 1H), 2.06 (m, 2H), 1.67 (m, 3H).
