実験手順
To a suspension of sodium hydride (60%, 0.05 g (1.25 mmol)) in 2.0 ml of DMF, 5-chloro-2-methylamino-3-nitropyridine (0.20 g (1.07 mmol)) was added under cooling with ice and with stirring. To the resulting mixture, after 15 minutes' stirring under cooling with ice, p-toluenesulfonyl chloride (0.23 g (1.21 mmol)) was added. The reaction mixture was stirred under cooling with ice for 30 minutes and then at room temperature for 30 minutes, poured into water and extracted with ethyl acetate. The extract was washed with water and saturated sodium chloride solution, successively, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was then subjected to silica gel column chromatography with ethyl acetate-hexane (1:3) as eluent, to give 0.16 g (44%) of the title compound as pale yellow crystals.
