実験手順

21.7 g of 4-Fluoro-naphthalen-1-ol were dissolved in 250 ml acetone. 39.0 g of potassium carbonate and 14.6 ml dimethyl sulphate were added at room temperature. The reaction was placed under nitrogen and stirred for 72 h. The mixture was filtrated; the solid washed with acetone, and the filtrate was concentrated to a viscous oil, which was taken up in ethyl acetate. This was washed with water and with brine, dried over sodium sulphate, filtered through celite and concentrated. The resulting oil was distilled using a Kugelrohr-apparatus, yielding 11.4 g of 4-fluoro-1-methoxynaphthalene.
