4-(4-Bromophenyl)butanoyl chloride → 4-{4-[4-(4-Bromo-phenyl)-butyrylamino]-phenyl}-4-oxo-butyric acid

Participants

Reaction Steps

In a manner similar to that described in Example 3, 4-(4-bromo-phenyl)-butyryl chloride (0.086 g, 0.00033 mol) was allowed to react with 4-(4-amino-phenyl)-4-oxo-butyric acid, methyl ester (0.052 g, 0.00025 mol), and the resulting intermediate was hydrolyzed to give 0.089 g of 4-{4-[4-(4-bromo-phenyl)-butyrylamino]-phenyl}-4-oxo-butyric acid as a yellow solid; MS-(AP+) MH+419.
