Procedure

A mixture of methyl 3-amino-4-chloro-2-[(3-hydroxypropyl)amino]benzoate (1.50 g, 5.80 mmol) and 1,5-dichloro-2-isothiocyanato-3-methylbenzene (1.64 g, 7.52 mmol) in tetrahydrofuran (15 mL) was stirred at 60° C. for 17 hr. The mixture was diluted with saturated aqueous sodium hydrogen carbonate 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 the title compound as a brown powder (2.18 g, 4.57 mmol, 79%).
