Reaction Steps

In analogy to example 83, step a) using 1-(6-Trifluoromethyl-pyrazin-2-yl)-1H-pyrazole-4-carboxylic acid (prepared as described in example 125) instead of 2-(trifluoromethyl)-4-pyridinecarboxylic acid (CAS 131747-41-6) and (−)-(S)-2-(4-Amino-3-chloro-phenyl)-morpholine-4-carboxylic acid tert-butyl ester (described in example 29a) instead of (+)—(R)-2-(4-Amino-2-fluoro-phenyl)-morpholine-4-carboxylic acid tert-butyl ester.
