Reaction Steps

Cyclopropylisocyanate (4 g, 0.048 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) and pyridine (0.01 mL, 0.126 mmol) in CH2Cl2 (5 mL). The mixture was stirred for 24 h, and then the solvent was removed in vacuo. Purification by flash chromatography (2% CH3OH/CH2Cl2) afforded the title compound (10 mg) as a solid. 1H NMR (400 MHz, CDCl3): δ 8.22 (s, 1H), 7.93 (d, 1H, J=8.8 Hz), 7.83 (m, 1H), 7.49 (d, 1H, J=8.8 Hz), 7.27-7.24 (m, 2H), 7.17 (s, 1H), 5.71 (dd, 1H, J=2.4 and 9.2 Hz), 4.04 (m, 1H), 3785 (m, 1H), 2.59 (m, 2H), 2.17-2.07 (m, 2H), 1.74 (m, 5H), 0.84 (q, 2H, J=5.2 Hz).
