Reaction Steps

The racemic 5-fluoro-2-{4-[1-({6-[4-(methylsulfonyl)phenyl]-3-pyridinyl}oxy)ethyl]-1-piperidinyl}pyrimidine (prepared as in Example 153) was subjected to Chiral HPLC [column: OJ-H, column mobile phase: 70% CO2: 30% MeOH (2 mL/min), pressure 140 bar, temperature 40° C., 254 nm] analysis and then separated to give two (R and S) enantiomers. The title compound was isolated as an off-white solid with Tr of 30.59 min (second eluting peak). The (R) absolute stereochemistry was assigned by Ab initio VCD analysis.
