実験手順

1-(5-Amino-2-chlorophenyl)ethanone (411 mg; synthesized by the process reported by Radziejewski et al., Heterocycles, vol. 26, pp. 1227-1238 (1987)) was dissolved in toluene (5 mL), and pyridine(235 μL) and methanesulfonyl chloride (225 μL) were added. The resulting mixture was stirred at room temperature for 50 minutes. After adding water (50 mL), the reaction mixture was extracted with ethyl acetate (500 mL). The organic layer was washed with an aqueous 1 N hydrochloric acid solution (50 mL) and saturated brine (50 mL) and then dried over anhydrous sodium sulfate (5 g). The solvent was distilled off under reduced pressure to yield the title compound (595 mg) as a colorless crystal.
