Dicyclohexylcarbodiimide → HCID 53793533, compound

Participants

Reaction Steps

The procedure described in Example 180 was repeated, except that (S)-2-(4-bromobenzenesulfonylamino)-4-methylthiobutanoic acid (7.86 g) and ethyl 4-aminophenylacetate (3.64 g) were condensed in dichloromethane (80 ml) in the presence of N,N'-dicyclohexylcarbodiimide (5.28 g). The reaction mixture was filtered, and the filtrate was concentrated. The resulting crude product was recrystallized from ethanol to obtain (S)-2-(4-bromobenzenesulfonylamino)-N-(4-(ethoxycarbonylmethyl)phenyl)-4-methylthiobutanamide (1.67 g).
