Versuchsvorschrift
The title compounds were prepared as white solids from EDCI coupling between 3-amino-azetidine-1-carboxylic acid tert-butyl ester and (3,5-bistrifluoromethyl-benzoylamino)-acetic acid (prepared by the method similar to Ingersoll, A. W. et. al., Organic Syntheses 1932, XII, 40-2) using the procedure described in Step C of Example 1.
