Reaction Steps

Tert-butyl3-{3-[6-azetidin-1-yl-2-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)pyridin-3-yl]-4-methoxyphenyl}-2,2-dimethylpropanoate (48 mg, 0.067 mmol) was dissolved in dichloromethane (1 mL). TFA (0.1 mL, 1.298 mmol) was added and the reaction was stirred at room temperature for 4 hours. The reaction was then concentrated and the residue was dissolved in methanol (1 mL). 4M KOH (0.333 mL, 1.330 mmol) was added, and the reaction was stirred for 10 min. at room temperature. Next, acetic acid (0.076 mL, 1.330 mmol) was added. The reaction was diluted with ethyl acetate (10 mL), washed with water (2×8 mL) and brine (8 mL), dried over sodium sulfate, filtered, and concentrated. The residue was purified by PTLC (50% ethyl acetate/hexanes) to afford 3-{3-[6-azetidin-1-yl-2-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)pyridin-3-yl]-4-methoxyphenyl}-2,2-dimethylpropanoic acid.
