Reaction Steps

3-(5-(4-Methylpiperidin-1-yl)-1H-benzo[d]imidazol-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-amine (50 mg, 0.116 mmol), 1H-benzo[d][1,2,3]triazol-1-ol (HOBt) (23.54 mg, 0.174 mmol), EDC (33.4 mg, 0.174 mmol) and sodium bicarbonate (9.76 mg, 0.116 mmol) was added to a solution of 2,2-difluorocyclopropanecarboxylic acid (14.18 mg, 0.116 mmol) in DMF (6 mL). The reaction mixture was stirred at room temperature for 24 h, and the solvent was removed in vacuo. Purification by flash chromatography (6% CH3OH/CH2Cl2) afforded the title compound (35 mg). 1H NMR: (400 MHz, CD3OD): δ 8.49 (s, 1H), 7.75 (m, 1H), 7.66 (d, 1H, J=8.8 Hz), 7.54 (bs, 1H), 7.06 (m, 2H), 5.84 (dd, 1H, J=2.8 and 9.2 Hz), 3.96 (m, 1H), 3.80 (m, 1H), 3.58 (m, 2H), 2.69 (m, 4H), 2.11 (m, 3H), 1.82 (m, 4H), 1.70 (m, 2H), 1.49 (m, 1H), 1.41 (m, 2H), 0.99 (d, 3H, J=6.0 Hz); ESI-MS [M+H]+: 535.2.
