実験手順

To a magnetically stirred suspension of sodium hydride (60% oil dispersion washed two times with hexane, 80 mg, 2.0 mmol) in 5 mL of dimethylformamide (DMF) under nitrogen was added methyl α-[3-(trifluoromethyl)benzylamino]-indole-3acetate (752 mg, 2.0 mmol) dissolved in 2 mL DMF. Stirring was continued at room temperature for 10 minutes. At the end of this time, 0.322 g (2.0 mmol) of parachlorobenzyl chloride was added and the reaction stirred at room temperature for one hour. The reaction was diluted with ether and the ether solution was washed two times with water. The ether extract was then washed with saturated brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give the crude product. Flash chromatography of the crude product with 100 g of silica gel and using hexane-ethyl acetate (4:10) as the eluent afforded 419 mg of the title compound.
