Reaktionsschritte

To a solution of 2-hydroxy-5-methyl-benzaldehyde (2.4 g, 18 mmol) (Aldrich) in N,N-dimethylformamide (30 mL) was added cesium carbonate (6 g, 18 mmol), potassium iodide (3 g, 18 mmol) and 2-bromoethyl acetate (7 g, 42 mmol), Aldrich). The reaction mixture was heated at 100° C. for 3 h. The mixture was cooled to room temperature and diluted with ethyl ether, washed with water, brine, separated, and concentrated. The residue was purified by chromatography (EtOAc:Hexanes=1:6) to give acetic acid 2-(2-formyl-4-methyl-phenoxy)-ethyl ester as a yellow oil (Yield 4 g, 100%).
