실험 절차

A mixture of methyl 3-amino-4-chloro-2-[(3-hydroxypropyl)amino]benzoate (13.1 g, 50.6 mmol) and 2,4-dichloro-1-isothiocyanatobenzene (13.4 g, 65.8 mmol) in tetrahydrofuran (150 mL) was stirred at room temperature for 3 days. The mixture was diluted with saturated aqueous sodium hydrogen, carbonate, concentrated in vacuo, and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was washed with diisopropyl ether to give methyl 4-chloro-3-{[(2,4-dichlorophenyl)carbamothioyl]amino}-2-[(3-hydroxypropyl)amino]benzoate as a colorless powder (19.6 g)
