実験手順

To a solution of 1-methanesulfonyl-5-chloro-spiro[indoline-3,3′-pyrrolidine] (725 mg) in acetonitrile (40 ml) were added diisopropylethylamine (0.66 ml) and 4-chlorocinnamyl chloride (467 mg). The resulting solution was stirred at room temperature for 12 hours, diluted with ethyl acetate, washed with water, brine, dried (Na2SO4) and concentrated in vacuo. The residue was purified by silica gel chromatography (eluent cyclohexane:ethyl acetate 6:4) to afford 1-methanesulfonyl-5-chloro-1′-[trans-3-(4-chlorophenyl)allyl]spiro[indoline-3,3′-pyrrolidine] (500 mg) which was characterised by its mass and NMR spectra. MS (ES+) 437/439 (M+H+).
