Reaction Steps

((S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide) (150 mg, 0.357 mmol), EDC (103 mg, 0.535 mmol), 3-(phenylsulfonyl)propanoic acid (84 mg, 0.393 mmol), and DMAP (65.4 mg, 0.535 mmol) in DCM (30 ml) were stirred at RT for 4 hours. The reaction mixture was washed with HCl 1N (2×) and NaHCO3 sat. sol. (2×); the organic layer was dried over Na2SO4 and evaporated to dryness. The residue was purified by trituration with iPr2O (10 ml). Further triturations with petroleum ether (15 ml) and Et2O (20 ml) were performed to afford (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-(3-(phenylsulfonyl)propanoyloxy)ethyl)pyridine
