Versuchsvorschrift

A suspension of N-(3-acetyl-4-hydroxy-phenyl)-acetamide (1.029 g, 5.3 mmol) in 15% HCl (1.5 ml, 6.2 mmol, 1.2 equ) was heated to reflux for 40 minutes, then cooled and neutralised with 10% aqueous ammonia. The precipitated solid was collected by filtration as 1-(5-amino-2-hydroxy-phenyl)-ethanone (0.677 g, 84%) a green solid.
