Procedure

Methyl 3-(4-{[2-(1-benzhydryl-5-chloro-2-{2-[(methylsulfonyl)oxy]ethyl}-1H-indol-3-yl)ethyl]sulfonyl}phenyl)benzoate (1 eq), sodium azide (5 eq), and DMF (0.05M) were placed together under N2 and heated to 60° C. After 1 hour the reaction was cooled and water was added. Extracted with EtOAc/Et2O mix and washed with water and brine and dried over sodium sulfate. Removed solvent to obtain methyl 3-[4-({2-[2-(2-azidoethyl)-1-benzhydryl-5-chloro-1H-indol-3-yl]ethyl}sulfonyl)phenyl]benzoate (light-yellow solid) in 99% yield.
