Versuchsvorschrift

The acid chloride from 6.7 g (14.7 mmol) of N-((1S)-1-ethoxycarbonyl-3-phenylpropyl)-N-(2,2,2-trichloroethoxycarbonyl)alanine (Example 7A) is dissolved in 25 ml CH2Cl2 and added dropwise to a solution of 6.3 g (14.6 mmol) of 4-(2,3-dichloro-4-((ethoxycarbonyl)-methoxy)benzoyl)methylene proline ethyl ester and 1.6 g (15.8 mmol) of triethylamine in 100 ml CH2Cl2. Further reaction and purification as in example 7A gives the desired amide.
