Procedure: Under an atmosphere of nitrogen, methyl iodide (1.35 g, 10 mmol) and potassium carbonate (4.39 g, 320 mmol) were added to a solution of 2′-amino-3′-hydroxyacetophenone (960 mg, 6 mmol, TCI Europe) in DMF (6 ml). The reaction mixture was stirred for 1 h at r.t., during which time the color of the mixture changed from light brown to dark green. The mixture was then worked up by extraction with H2O/ethyl acetate, drying of the organic phase (Na2SO4), and evaporation of solvent. The title compound (960 mg, 92%) was isolated from the residue by column chromatography (silica gel, heptan/ethyl acetate=100/0-70/30). The mixture was then worked up by extraction with H2O/ethyl acetate drying of the organic phase (Na2SO4), and evaporation of solvent
