実験手順
A solution of 5-chloro-2-fluorobenzene-1-sulfonyl chloride (2.0 g) in tetrahydrofuran (30 ml) was added to a solution of tert-butylamine (9.15 ml) in tetrahydrofuran (70 ml) at 0° C. The reaction mixture was allowed to warm to room temperature and stirred for 2 h. The precipitate was removed by filtration and the filtrate was concentrated in vacuo to give N-tert-butyl-5-chloro-2-fluoro-benzenesulfonamide (2.2 g, 95% yield) as a white solid.
