実験手順

A solution of indole-2-carboxylic acid (79 mg) and 1,1'-carbonyldiimidazole (80 mg) in dry tetrahydrofuran (2.0 mL) is stirred at ambient temperature for one hour, and a solution of (S)-(-)-N-[[2-oxo-3-[4-(4-piperidinyl)-3-fluorophenyl]-5-oxazolidinyl]methyl]acetamide (EXAMPLE 20, 150 mg) in dry tetrahydrofuran (6.0 mL) is added. The mixture is then stirred at ambient temperature for 19 hours, concentrated under reduced pressure, diluted with methylene chloride (20 mL), washed with saturated aqueous sodium bicarbonate (10 mL), water (10 mL) and saline (10 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the crude product which is chromagraphed on silica gel (70-230 mesh, 10 g), eluting with methanol/methylene chloride (7.5/92.5). Pooling and concentration of those fractions with an Rf =0.67 by TLC (methanol/chloroform, 10/90) and recrystallization from chloroform/diethyl ether gives the title compound, mp 223-225° C.
