Procedure

The title compound was synthesized in analogy to Example 1, using 5-cyclopropyl-6-cyclopropylmethyloxy-pyridine-2-carboxylic acid (Example 42a) and 2-cyclopropyl-1-methyl-1-(5-methyl-[1,2,4]oxadiazol-3-yl)-ethylamine (Example 357e) as starting materials. The product was isolated by chiral chromatography on Reprosil Chiral NR using heptane/10% 2-propanol as eluent. The (−)-enantiomer was isolated. LC-MS (UV peak area/ESI) 100%, 397.2244 (M+H)+, αD20 (MeOH)=−22.3°.
