실험 절차

To a solution of 2-chloro-5-ethylbenzenesulfonyl chloride (0.41 g, 1.7 mmol, the product of Step A) in tetrahydrofuran (30 mL) was added 30% ammonium hydroxide (0.41 mL, 3.5 mmol) dropwise. The reaction mixture was stirred for 15 minutes, during which time a suspension formed. To this mixture water (10 mL) was added, and the tetrahydrofuran was evaporated under reduced pressure to precipitate a solid. The solid was dissolved in diethyl ether, dried over magnesium sulfate, and concentrated under reduced pressure. Diethyl ether and hexane were added to precipitate a solid. The solid was isolated by filtration to afford 190 mg of the title compound. 1H NMR (CDCl3) δ 7.95 (s, 1H), 7.43 (d, 1H), 7.35 (d, 1H), 5.08 (br s, 2H), 2.71 (q, 2H), 1.25 (t, 3H).
