In a manner similar to that described in Example 3, propionyl chloride (0.029 g, 0.00032 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 0.027 g of 4-oxo-4-[4-(propionylamino)-phenyl]-butyric acid as an off-white solid; MS-(AP+) MH+250.
