実験手順

(rac)-4-{6-Methyl-2,5-dioxo-1-[3-(trifluoromethyl)phenyl]-2,3,4,5,6,7-hexahydro-1H-pyrrolo[3,4-d]pyrimidin-4-yl}-3-(methylsulfonyl)benzonitrile (Example 34, 190 mg) was separated into the enantiomers by preparative HPLC chromatography on a chiral phase [column: Daicel Chiralpak IC, 5 μm, 250 mm×20 mm; sample preparation: the sample was dissolved in 70 ml of methanol/acetonitrile/MTBE 25:10:35; injection volume: 1 ml; mobile phase: MTBE/methanol 75:25 (0-7 min); flow rate: 15 ml/min; temperature: 30° C.; detection: 220 nm]. This gave 97 mg (100% of theory, >99.0% ee) of the 4S enantiomer. The enantiomeric excess (ee value) was determined chromatographically [column: Daicel Chiralpak IC, 5 μm, 250 mm×4.6 mm; mobile phase: MTBE/methanol 75:25; flow rate: 1 ml/min; temperature: 25° C.; detection: 220 nm; R=6.62 min].
