Reaction Steps

(S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (80 mg; 0.19 mmol) was dissolved in DMF (2 ml), then 2-(tert-butoxycarbonylamino)acetic acid (70 mg, 0.4 mmol), EDC (60 mg, 0.3 mmol), and DMAP (30 mg, 0.25 mmol) were added. The reaction was stirred at RT for 6 hours, then it was diluted with water and extracted with EtOAc. The organic phase was extracted with HCl 1M and with K2CO3 sat, dried over Na2SO4 and evaporated under vacuum to give 80 mg of the desired compound (Yield: 74%).
