Procedure

The racemic 1-methylethyl 4-[1-({6-[4-(methylsulfonyl)phenyl]-3-pyridinyl}oxy)propyl]-1-piperidinecarboxylate (prepared as in Example 142) was subjected to Chiral HPLC [column: AS-H, column mobile phase: 80% CO2: 20% MeOH (2 mL/min), pressure 140 bar, temperature 40° C., 215 nm] analysis and then separated to give two (R and S) enantiomers. The title compound was isolated as a white foam with Tr of 10.65 min (first eluting peak). The (R) absolute stereochemistry was assigned by Ab initio VCD analysis.
