実験手順
The title compounds were prepared by chiral separation of (S)-4-(4-chloro-3-trifluoromethoxy-phenyl)-1-[4-((S)-4-hydroxy-6-aza-spiro[2.5]oct-6-yl)-4-oxo-butyl]-3-methyl-piperazin-2-one (61% ds) on a Reprosil Chiral NR, (40% EtOH in n-heptane) to give 25% of (R)-4-(4-chloro-3-trifluoromethoxy-phenyl)-1-[4-((S)-4-hydroxy-6-aza-spiro[2.5]oct-6-yl)-4-oxo-butyl]-3-methyl-piperazin-2-one (example 63) as white foam, MS: 504.19 (MH+, Cl) and 33% of (S)-4-(4-chloro-3-trifluoromethoxy-phenyl)-1-[4-((S)-4-hydroxy-6-aza-spiro[2.5]oct-6-yl)-4-oxo-butyl]-3-methyl-piperazin-2-one (example 62) as white foam, MS: 504.19 (MH+, Cl).
