Reaction Steps

(S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide 30 mg, 0.071 mmol), 2-(N-(4-(methylthio)phenyl)methyl-sulfonamido)acetic acid (39.3 mg, 0.143 mmol), DMAP (17.44 mg, 0.143 mmol), and EDC (41.1 mg, 0.214 mmol) were dissolved in DMF (1.5 ml). The reaction was stirred at RT overnight to achieve completion. The reaction mixture was diluted with water and extracted with EtOAc. The organic phase was washed with HCl 1N, Na2CO3 sat. sol. and brine, dried over Na2SO4 and concentrated under vacuum. The crude product was purified by Preparative reverse-phase HPLC to give (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-(2-(N-(4-(methylthio)phenyl)methylsulfonamido)-acetoxy)ethyl)pyridine 1-oxide (20 mg, 41.3% yield).
