Reaction Steps

(S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (100 mg, 0.24 mmol) and (S)-2-(tert-butoxycarbonyl-amino)-3-(4-(methylsulfonyloxy)phenyl)propanoic acid (172 mg, 0.48 mmol) were dissolved in DMF (3 ml). DMAP (35 mg, 0.29 mmol) and EDC (92 mg, 0.48 mmol) were added, and the mixture was stirred at RT for 3 hours, then was quenched with HCl 1N and extracted with EtOAc. The organic layer was washed with HCl 1N and NaHCO3 sat. sol., then was dried over Na2SO4 and evaporated under vacuum to give 155 mg (85%) of the title compound which was employed in the next step without any further purification. MS/ESI+ 761.14 [MH]+.
