Procedure

Ethyl 2-(4-acetamidophenoxy)propanoate (5.0 g, 2.0 mmol) is hydrolyzed by refluxing for 6 hours at 80° C. with ethanol (10 mL) and 3 drops of concentrated hydrochloric acid. The reaction is concentrated under reduced pressure to obtain ethyl 2-(4-aminophenoxy)propanoate (0.4 g) (yield 95%).
