1,2-Dichloroethane → N-(3-(1H-benzo[d]imidazol-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)-4,4-difluorocyclo hexane carboxamide

Participants

Reaction Steps

4,4-Difluorocyclohexanecarboxylic acid (8 mg, 0.048 mmol), HOBt (9 mg, 0.066 mmol), EDC (13 mg, 0.068 mmol) and sodium bicarbonate (4 mg, 0.047 mmol) was added to a solution of 3-(1H-benzo[d]imidazol-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-amine (15 mg, 0.045 mmol) in DMF (5 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 (10 mg). 1H NMR (400 MHz, CD3OD): δ 8.51 (s, 1H), 7.74 (m, 2H), 7.66 (m, 2H), 7.28 (m, 2H), 5.92 (d, 1H, J=8.8 Hz), 4.01 (m, 1H), 3.84 (m, 1H), 2.66 (m, 1H), 2.54-2.44 (m, 2H), 2.17 (m, 3H), 2.01-1.70 (m, 9H).
