The title compound was synthesized in analogy to Example 63b, using 5-Cyclopropyl-4-(2,2,2-trifluoro-ethoxy)-pyridine-2-carboxylic acid (Example 48c) and 2-Cyclopropyl-1-methyl-1-(5-methyl-[1,2,4]oxadiazol-3-yl)-ethylamine (Example 66e) as starting materials and the racemate was isolated (43 mg, 32%) as a colorless oil. The racemate was separated into its enantiomers by preparative chiral HPLC (Chiralpak AD, isopropanol/heptane) and the title compound was the first enantiomer collected and isolated as a colorless oil; MS (ESI, m/z): 425.5 (M+H+). The collected enantiomer shows levorotation properties according to the observed optical activity measured during preparative chiral HPLC.
