Procedure

The title compound (65 mg, 43% yield) was obtained enantiomerically pure (>99% ee) after chiral preparative chromatography (system: MGII preparative SFC; column: Chiralpak AD-H, 30×250 mm; mobile phase: scCO2/iPrOH 75:25; flow: 50 mL/min; temperature: 38° C.; detection UV: 220 nm) of the racemic mixture of 4-(4-chloro-2-fluorophenyl)-5-(3,8-dimethyl-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-1-isopropyl-3-methyl-4,5-dihydropyrrolo[3,4-c]pyrazol-6(1H)-one (Example 168).
