実験手順

Allyl bromide (11 g, 90.8 mmol.) was added, under argon atmosphere, to a mixture of N-[2-(5-hydroxyindol-3-yl)ethyl]propionamide (20.0 g, 92.5 mmol.), cesium carbonate (31.6 g, 97 mmol.) and N,N-dimethylformamide (150 mL) at 0° C. The reaction mixture was stirred for one hour at 50° C., to which was added water. The product was extracted with ethyl acetate. The extract solution was washed with water and dried. The solvent was then distilled off to leave the title compound (yield 20.0 g, 79.4%) as an oily product. This product was used, without further purification, for the subsequent reaction.
