Procedure

[2-(tert-Butyl-dimethyl-silanyloxy)-ethyl]-[2-(1H-indol-3-yl)-ethyl]-amine (compound E2) (830 mg, 2.60 mmol) is dissolved in ethanol (200 ml). (E)-3-[1-(4-bromomethyl-benzenesulfonyl)-1H-pyrrol-3-yl]-acrylic acid tert-butyl ester (compound D4) (1.01 g, 2.37 mmol) is added and the mixture is stirred for 43 hours and evaporated. The residue is purified by a silica gel flash chromatograph using petrol ether-ether eluent.
