Reaction Steps
The title compound was synthesized in analogy to Example 1, using 5-cyclopropyl-6-cyclopropylmethyloxy-pyridine-2-carboxylic acid (Example 42 a) and (αR)-α-amino-N,N-dimethyl-benzeneacetamide hydrochloride (1:1) (CAN 129157-29-5) as starting materials. Racemization occurred during the synthesis and the product was isolated by chiral chromatography on Reprosil Chiral NR using heptane/20% ethanol as eluent. The (−)-enantiomer was isolated. LC-MS (UV peak area/ESI) 100%, 394.2126 (M+H)+, αD20 (MeOH)=−44.9°.
