Reaction Steps

The procedure described in Example 180 was repeated, except that (S)-2-(4-bromobenzenesulfonylamino)-3-phenylpropanoic acid (2 g) and ethyl 4-aminobenzoate were condensed in dichloromethane (100 ml) in the presence of N,N'-dicyclohexylcarbodiimide (1.29 g). The reaction mixture was filtered, and the filtrate was concentrated. The resulting crude product was recrystallized from a mixture of carbon tetrachloride and ethanol to obtain (S)-2-(4-bromobenzenesulfonylamino)-N-(4-ethoxycarbonylphenyl)-3-phenylpropanamide (623 mg).
