Procedure

To methyl 4-{2-[2-(2-aminoethyl)-1-benzhydryl-5-chloro-1H-indol-3-yl]ethoxy}benzoate (1.0 equiv) and sat. NaHCO3 (0.14 M) in CH2Cl2 (0.07 M) was added α-toluenesulfonyl chloride (1.0 equiv). After 1 h the mixture was poured into saturated sodium bicarbonate and extracted with CH2Cl2. The combined organic phase was washed with brine, dried over sodium sulfate and purified by column chromatography (gradient elution using 20% EtOAc-hexanes→50% EtOAc-hexanes) to afford 86% of the desired product.
