Using a method similar to the procedure described for the preparation of 4-[4-(2-amino-phenyl)-oxazol-2-yl]-butyric acid; hydrolysis of 3-[4-(2-amino-phenyl)-oxazol-2-yl]-propionic acid methyl ester (4.8 g, 19.5 mmol) gives 3-[4-(2-amino-phenyl)-oxazol-2-yl]-propionic acid (3.84 g, 85%) after chromatography over silica gel (MeOH/CH2Cl2). MS (ES): (M+1)+ 233.1 m/z.
