1,4-Dimethylpiperidine-4-carboxylic acid (3 mg, 0.019 mmol), HOBt (4 mg, 0.029 mmol), EDC (5.5 mg, 0.028 mmol) and sodium bicarbonate (1.6 mg, 0.019 mmol) were added to a solution of 3-(1H-benzo[d]imidazol-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-amine (6.4 mg, 0.019 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 (3.5 mg) as a solid. 1H NMR (400 MHz, CD3OD): δ 8.54 (s, 1H), 7.77 (m, 1H), 7.71 (m, 2H), 7.38 (m, 2H), 7.29 (m, 2H), 5.94 (d, 1H, J=8.0 Hz) 4.00 (m, 1H), 3.85 (m, 1H), 3.46 (m, 2H), 2.89 (s, 3H), 2.69 (m, 2H), 2.56 (m, 1H), 2.15 (m, 3H), 1.86 (m, 3H), 1.72 (m, 3H), 1.46 (s, 3H).
