Procedure

A solution of (R)-(-)-4-[4-[5-hydroxymethyl)-2-oxo-3-oxazolidinyl]-2-fluorophenyl]-1-piperidinecarboxylic acid 1,1-dimethylethyl ester (EXAMPLE 20, Step 5, 970 mg) and triethylamine (0.50 mL) in dry methylene chloride (9.5 mL) at 0° C. under N2 is treated with methanesulfonyl chloride (0.20 mL) dropwise. The resulting mixture is stirred at 0° C. for one hour, diluted with methylene chloride (40 mL), washed with water (10 mL), saturated aqueous sodium bicarbonate (10 mL) and saline (10 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound, mp 163-165° C.

Workup

  1. washwashed with water (10 mL), saturated aqueous sodium bicarbonate (10 mL) and saline (10 mL)
  2. dry with materialdried over anhydrous sodium sulfate
  3. concentrationconcentrated under reduced pressure
