Reaction Steps
The title compound was synthesized in analogy to Example 1, using 5-cyclopropyl-6-cyclopropylmethyloxy-pyridine-2-carboxylic acid (Example 42a) and 2-amino-propanenitrile monohydrochloride (CAN 2134-48-7) as starting materials. The product was isolated by chiral chromatography on Reprosil Chiral NR using heptane/15% ethanol as eluent. The (−)-enantiomer was isolated. LC-MS (UV peak area/ESI) 100%, 286.1552 (M+H)+, αD20 (MeOH)=−9.6°.
