Procedure

MeSO2Cl (0.03 mL, 0.39 mmol) and Et3N (0.07 mL, 0.48 mmol) were added to a solution of the alcohol from step 5 (0.11 g, 0.19 mmol) in dichloromethane (8 mL) at 0° C. Reaction was stirred at 0° C. for one hour and then warmed to room temperature and stirred an additional hour. Reaction solution was concentrated by rotary evaporation. Obtained 0.123 g of 4-{2-[1-Benzhydryl-5-chloro-2-(2-methanesulfonyloxy-ethyl)-1H-indol-3-yl]-ethoxy}-2-methoxy-benzoic acid methyl ester in quantitative yield.
