실험 절차

Benzenesulfonyl chloride (1.74 mL, 13.57 mmol) and DIEA (0.34 mL, 2.49 mmol) were added to a solution of 3,5-dichloroaniline (2.0 g, 12.34 mmol) in DCM (50 mL). The resulting solution was stirred at room temperature for 48 h, during which a precipitate was formed. The reaction mixture was then evaporated to dryness and purified by flash column chromatography (ethyl acetate/hexanes=1/9) to give TC-IV-145 (1.90 g, 51%) as a yellow solid.
