Versuchsvorschrift

To a stirred solution of (4-nitro-phenyl)-acetic acid (3 g, 16.4 mmol) in ethanol (30 mL) was added sulphuric acid (1 mL) and the reaction mixture was heated to reflux for 16 hours. The reaction mixture was neutralized with 2N aq. NaOH solution and extracted with EtOAc (3×50 mL). The combined organic layers were dried (Na2SO4) and evaporated in vacuo to afford the title compound as a light yellow oil in 98% yield, 3.4 g.
