Versuchsvorschrift

To a solution of N-(3-hydroxy-phenyl)-acetamide (5 g, 33.1 mmol) in acetone (50 ml) were added K2CO3 (5.49 g, 39.8 mmol) and bromo-acetonitrile (4.37 g, 36.4 mmol). The reaction mixture was heated to 100° C. for 3 h, filtered and the acetone layer evaporated in vacuo. This residue was dissolved in EtOAc (100 ml) and washed with 1M NaOH (10 ml×2). The organic layer was dried (Na2SO4), filtered and the solvent removed in vacuo. The crude residue was purified by column chromatography eluting with 80% EtOAc in heptane to give the title compound.
