Procedure

To a solution of 2-(5-(N-(tert-butoxycarbonyl)methylsulfonamido)-1H-indol-1-yl)acetic acid (120 mg, 0.326 mmol) in DCM (10 ml), (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (137 mg, 0.326 mmol), EDC (187 mg, 0.977 mmol) and DMAP (19.90 mg, 0.163 mmol) were added, and the mixture was reacted at room temperature for 6 hours. The mixture was portioned between DCM and 1N HCl (50 ml) and the desired compound was extracted with DCM (3×50 ml). Crude (S)-4-(2-(2-(5-(N-(tert-butoxycarbonyl)-methylsulfonamido)-1H-indol-1-yl)acetoxy)-2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)ethyl)-3,5-dichloropyridine 1-oxide was obtained and used in the next step without any additional purification (170 mg, 0.221 mmol, 68% yield). MS/ESI+ 770.1 [MH]+.
