A 100 mg (0.23 mM) quantity the less polar isomer of (4S,5R)-N-(t-butylamino-carbonyl)-2-(2,4-dimethoxyphenyl)-4-phenyl-5-oxazolidinecarboxylic acid methyl ester (Preparation 57, 5Ka) is stirred at room temperature under nitrogen in 3 mL MeOH. To this is added 0.1 mL water and 43 mg (0.31 mM) potassium carbonate. After 1 hour, TLC shows no starting material left. Store in freezer overnight. The next morning the solvent is evaporated to give (4S, 5R)-N-(t-butylaminocarbonyl)-2-(2,4-dimethoxyphenyl)-4-phenyl-5-oxazolidinecarboxylic acid potassium salt (6Ka).
