Dicyclohexylcarbodiimide → HCID 54432559, compound

Participants

Reaction Steps

The procedure described in Example 180 was repeated, except that (S)-2-(4-bromobenzenesulfonylamino) hexanoic acid (3.64 g) and ethyl 3-aminobenzoate (1.47 ml) were condensed in dichloromethane (40 ml) in the presence of N,N'-dicyclohexylcarbodiimide (2.57 g). The reaction mixture was filtered, and the filtrate was concentrated. The resulting crude product was recrystallized from toluene to obtain (S)-2-(4-bromobenzenesulfonylamino)-N-(3-ethoxycarbonylphenyl)hexanamide (1.85 g).
