Reaction Steps

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