実験手順

The racemic sulfoxide 2-[2-fluoro-4-(methylsulfinyl)phenyl]-5-[({1-[3-(1-methylethyl)-1,2,4-oxadiazol-5-yl]-4-piperidinyl}methyl)oxy]pyridine (prepared as in Example 176, 195 mg) was subjected to Chiral HPLC [column: Chiralpak AS-H, column mobile phase: 65% CO2: 35% (80% MeOH: 20% CHCl3) (2 mL/min), pressure 140 bar, temperature 30° C., 280 nm] analysis and then separation to give two (R and S) enantiomers. The title compound (32 mg) was isolated as an off-white solid with Tr of 11.25 min (first eluting peak). The (R) absolute stereochemistry was assigned by Ab initio VCD analysis.
