Methyl 1-allyl-3-cyclohexyl-2-(4-methoxy-2-{[(triisopropylsilyl)oxy]methyl}phenyl)-1H-indole-6-carboxylate (1 eq.) was dissolved in THF (0.28M solution) and a 1M solution of tetrabutylammonium fluoride in THF (1 eq.) was added. The mixture was left stirring at RT for 2 h, then all volatiles were evaporated in vacuo and the residual material was dissolved in Et2O. The solution was washed with 1N HCl, saturated aq. NaHCO3 solution and with brine. The organic phase was dried over Na2SO4 and evaporated in vacuo. The residual material was purified by flash chromatography (PE:EtOAc, 8:2). After evaporation of the solvents the product was obtained as colorless foam (88%). MS (ES+): 434.2 (M+H+).
