Reaction Steps

EDC (82 mg, 0.429 mmol) was added to a solution of compound (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (120 mg, 0.286 mmol), 2-(4-(cyclopropylmethoxy)-3-(morpholinomethyl)-benzoyloxy)acetic acid (300 mg, 0.859 mmol) and DMAP (18 mg, 0.143 mmol) in DCM (1 ml) at RT under nitrogen atmosphere. The mixture was stirred at RT overnight. The mixture was then diluted with DCM and washed with NaHCO3 sat. sol., HCl 0.1N and brine. The organic phase was dried over Na2SO4, and the solvent was evaporated. The crude was purified through Preparative HPLC to give (S)-3,5-dichloro-4-(2-(2-(4-(cyclopropylmethoxy)-3-(morpholinomethyl)-benzoyloxy)acetoxy)-2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-ethyl)pyridine 1-oxide (150 mg, 70% yield).
