Reaction Steps

(E)-3-{1-[4-({[2-(tert-Butyl-dimethyl-silanyloxy)-ethyl]-[2-(1H-indol-3-yl)-ethyl]-amino}-methyl)-benzenesulfonyl]-1H-pyrrol-3-yl}-N-(tetrahydro-pyran-2-yloxy)-acrylamide (compound B 14) (120 mg, 0.169 mmol) is dissolved in THF (20 ml). Then it is added tetrabutylammonium fluoride (203 μl, 0.203, 1 M in THF) and triethylamine (47 μl, 0.338 mmol) and the mixture is stirred for 17 hours. After addition of water (50 ml) and extraction with ethyl acetate the organic phase is dried over sodium sulfate, filtrated and evaporated. The crude product is purified by a silica gel flash chromatography using dichloromethane-methanol eluent.
