実験手順
3-Hydroxy-5-(pentafluorosulfanyl)benzoic acid (O5.007; 3.0 g) was dissolved in absolute DMF (75 ml). Then iodomethane (3.6 ml) was added while stirring, followed by finely powdered potassium carbonate (6.3 g). After stirring at 40° C. for 5 hours, the mixture was cooled and admixed with water (250 ml). The mixture was then extracted four times with ether (100 ml). The combined extracts were each washed once with 1 N sodium hydroxide solution (75 ml) and water (100 ml), dried over magnesium sulfate, filtered and concentrated. 2.9 g of the desired compound were obtained.
