Reaction Steps

To a solution of 4-((S)-2-((R)-5-acetoxy-2-aminopentanoyloxy)-2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)ethyl)-3,5-dichloropyridine 1-oxide (205 mg, 0.354 mmol) dissolved in DCM (2.5 mL), pyridine (58 μl, 0.710 mmol) and 3,4-dimethoxybenzene-1-sulfonyl chloride (168 mg, 0.710 mmol) were added. The mixture was stirred at RT for 48 hours. The mixture was then diluted with DCM and washed with NaHCO3 sat. sol., HCl 0.1M and brine. The organic phase was dried over Na2SO4, and the solvent was evaporated, to yield 284 mg of a yellow solid which was purified by preparative reverse-phase HPLC to yield 42 mg of the title compound.
