실험 절차

To a solution of 5-(difluoromethoxy)-3-iodo-1H-indazole (1 g, 3.2 mmol) in DMF (25 mL) was added K2CO3 (1.8 g, 12.8 mmol) and 3-chloro-N,N-dimethylpropan-1-amine (1.1 g, 6.4 mmol), after the addition, the reaction mixture was stirred at 80° C. for 4 hour. After cooling to room temperature, H2O (25 mL) was added and product extracted with ethyl acetate (100 mL). The organic layer was washed with H2O (100 mL), brine (100 mL), dried over Na2SO4 and concentrated under reduced pressure, the residue was purified by column chromatography (silica gel, 200-300 mesh, eluting with dichloromethane/CH3OH=10:1) to give 3-(5-(difluoromethoxy)-3-iodo-1H-indazol-1-yl)-N,N-dimethylpropan-1-amine (1.1 g, 78.5%) as yellow oil. 1H NMR (300 MHz, CDCl3): δ 7.46-7.42 (m, 1H), 7.27-7.17 (m, 2H), 6.87-6.29 (t, 1H, J=73.8 Hz), 4.47-4.41 (m, 2H), 2.24-2.18 (m, 8H), 2.08-2.03 (m, 2H). LCMS: (M+H)+=396.
