Versuchsvorschrift

250 mg (0.611 mmol) of 1-[(4-cyanopiperidin-1-yl)carbonyl]-5-[4-(trifluoromethyl)phenyl]piperidine-3-carboxylic acid (Example 100A) and 106 mg (0.672 mmol, 75% pure) of N′-hydroxy-3-methoxypropanimidamide (Example 64A) were reacted according to the General Method 1. Enantiomer separation of the racemate according to Method 16D gave 77.0 mg of the title compound from Example 277 and 70.0 mg of the title compound from Example 278 (47% of theory).
