실험 절차

A mixture of 2.0 g (9.4 mmol) 1-(6-chloro-1H-indol-3-yl)-2,2,2-trifluoro-ethanone, 4.59 g (14.1 mmol) cesium carbonate and 2.14 g (10.4 mmol) 3,5-difluorobenzyl bromide in 90 ml acetonitrile was heated at 80° C. for 3 h. After cooling to room temperature addition of 150 ml water was followed by extraction with three 150-ml portions of tert-butyl methyl ether. The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo. The residue was triturated in 30 ml hot cyclohexane. Filtration gave 2.2 g (64%) of the crude title compound as light brown solid.
