Reaction Steps
A mixture of 2-(3-(N-(tert-butoxycarbonyl)methylsulfonamido)-4-methoxybenzoyloxy)acetic acid (0.192 g, 0.476 mmol), (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (0.200 g, 0.476 mmol), EDC (0.274 g, 1.428 mmol), and DMAP (0.058 g, 0.476 mmol) in DCM (20 ml) was stirred at RT for 2 hours. The mixture was washed with HCl 1N and with NaHCO3 5%; the organic layer was dried over Na2SO4, and the solvent was removed. The crude was purified by flash chromatography on silica gel cartridge (DCM:MeOH=99:1) to afford (S)-4-(2-(2-(3-(N-(tert-butoxycarbonyl)methylsulfonamido)-4-methoxybenzoyloxy)acetoxy)-2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)ethyl)-3,5-dichloropyridine 1-oxide (0.296 g, 0.367 mmol, 77% yield, MS/ESI+ 805.0 [MH]+).
