HCID 58002475HCID 58002475, compoundYield 29%

Procedure

250 mg (0.644 mmol) of 1-(1,3-thiazolidin-3-ylcarbonyl)-5-[4-(trifluoromethyl)phenyl]piperidine-3-carboxylic acid (Example 102A) and 52.5 mg (0.708 mmol) of N′-hydroxyethanimidamide were reacted according to the General Method 1. Enantiomer separation of the racemate according to Method 16D gave 38.0 mg of the title compound from Example 315 and 41.0 mg of the title compound from Example 316 (29% of theory)
