Reaction Steps
2,2-Difluorocyclopropanecarboxylic acid (8 mg, 0.065 mmol), HOBt (12 mg, 0.089 mmol), EDC (17 mg, 0.089 mmol) and sodium bicarbonate (56 mg, 0.059 mmol) were added to a solution of 3-(1H-benzo[d]imidazol-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-amine (20 mg, 0.059 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 as a solid in a 50% yield. 1H NMR (400 MHz, CD3OD): δ 8.51 (s, 1H), 7.77 (m, 1H), 7.67 (m, 3H), 7.27 (m, 2H), 5.86 (d, 1H, J=7.6 Hz), 4.00 (m, 1H), 3.81 (m, 1H), 2.74-2.61 (m, 2H), 2.13 (m, 3H), 1.84 (m, 2H), 1.69 (m, 2H).
