実験手順

To a solution of [3-(methoxy)phenyl](7-trifluoromethyl-1H-indazol-3-yl)methanone (0.27 g, 0.85 mmol) in 5 mL DMF was added in one portion sodium hydride (0.034 g, 0.85 mmol, 60% in oil). After the gas evolution ceased, 2-iodopropane (0.10 mL, 1.0 mmol) was added and the reaction was stirred at ambient to 50° C. for 24 hours. The cool reaction mixture was partitioned with EtOAc and 1 N HCl. The organic phase was washed with brine and dried (Na2SO4). Removal of the solvent in vacuo afforded the crude product which was purified by flash chromatography (silica gel, hexane/EtOAc, 9:1) to give the title compound (0.183 g) as an oil.
