실험 절차
To dichloromethane 3.0 mL solution of tert-butyl 4-amino-2-(4-fluoroanilino)benzoate 40 mg were added triethylamine 0.064 mL, benzothiophene-3-carbonyl chloride 55 mg and dichloromethane 1.5 mL at room temperature, and it was stirred at same temperature for 2 hours. Aminomethylated-polystyrene 250 mg was added to the reaction mixture, and it was stirred at room temperature for 4 hours. Saturated sodium hydrogen carbonate aqueous solution was added to the reaction mixture, and insoluble matter was filtrated. The organic layer was separated and collected, and the solvent was removed under reduced pressure. The obtained residue was refined by silica gel column chromatography [Trikonex company, Flash Tube 2008, eluent; hexane:ethyl acetate=4:1] to give tert-butyl 4-(benzothiophene-3-carboxamido)-2-(4-fluoroanilino)benzoate.
