Procedure

2-(4-Acetamidophenyl)-2-ethoxyacetic acid (7.54 g, 31.8 mmol) was heated with hydrazine monohydrate (40 ml) for 16 hr, the mixture cooled then concentrated in vacuo The residual oil was then purified by silica column chromatography (20-40% methanol in CH2Cl2 eluent) to give (±)-2-ethoxy-2-(4′-aminophenyl)-acetic acid (2.3 g, 37%) as a white foam.
