실험 절차

To a stirred solution of tert-butyl {2-[(2,6-diaminophenyl)amino]ethyl}carbamate (5.00 g, 18.8 mmol) in ethanol (38 mL) was added methyl 2-(2,4-dichlorophenyl)-2-hydroxyethanimidoate hydrochloride (5.59 g, 20.7 mmol) at room temperature. After 12 h, the reaction mixture was diluted with aqueous sodium hydrogen carbonate and water. The resultant mixture was extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel eluting with ethyl acetate to give the title compound as a brown amorphous solid (8.46 g, 18.7 mmol, 99%).
