Versuchsvorschrift

(S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (30 mg, 0.071 mmol), 2-(3-(N-(2-amino-2-oxoethyl)methylsulfonamido)-4-methoxybenzoyloxy)acetic acid (51.4 mg, 0.143 mmol), DMAP (15 mg, 0.123 mmol), and EDC (100 mg, 0.522 mmol) were dissolved in DMF (2 ml). The reaction was stirred at RT for 3 hours to achieve completion. The reaction mixture was diluted with Water, and the precipitate was washed with water, dissolved in EtOAc and extracted with HCl 1N, Na2CO3 sat. sol. and brine. The organic phase was dried over Na2SO4 and concentrated under vacuum. The crude product was crystallized in EtOH to give (S)-4-(2-(2-(3-(N-(2-amino-2-oxoethyl)methylsulfonamido)-4-methoxybenzoyloxy)acetoxy)-2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)ethyl)-3,5-dichloropyridine 1-oxide (20 mg, 0.026 mmol, 36.7% yield).
