実験手順
Methanesulfonyl chloride (3.2 mL, 42 mmol) was slowly added to a stirring solution of furfurylamine (4.2 g, 43.2 mmol) and triethylamine (6 mL, 43 mmol) in anhydrous methylene chloride (110 mL). The reaction was stirred overnight at ambient temperature and then diluted with ethyl acetate. The organic solution was successively washed with 1N aqueous hydrochloric acid three times, saturated aqueous sodium bicarbonate and saturated aqueous sodium chloride solutions, dried (anhydrous sodium sulfate), and filtered. The solution was concentrated under reduced pressure to give the desired product as a tan liquid (6.6 g, 89%). 1H NMR (CDCl3, 300 MHz) δ 7.39-7.38 (m, 1H), 6.33-6.31 (m, 2H), 5.02 (br s, 1H), 4.33-4.31 (d, 2H, J=6 Hz).
