Procedure

To methyl 4-{2-[2-(2-aminoethyl)-1-benzhydryl-5-chloro-1H-indol-3-yl]ethoxy}benzoate (Step 6, Example 1) (1.0 equiv) and Et3N (3.0 equiv) or pyridine (3.0 equiv) in CH2Cl2 (0.05 M) was added 1-methylimidazole-4-sulfonyl chloride (1.2 equiv). The reaction was monitored by TLC (10% MeOH—CH2Cl2) and was heated if necessary. After 30 min 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 to afford 92% of the desired product.
