Procedure

A solution of methyl 3-amino-4-chloro-2-[(4-hydroxybutyl)amino]benzoate (2.00 g, 7.33 mmol) and 2-chloro-1-isothiocyanato-4-methoxybenzene (2.94 g, 14.7 mmol) in tetrahydrofuran (20 mL) was stirred for 36 h at 70° C. The reaction mixture was concentrated in vacuo and purified by flash column chromatography on silica gel eluting with a 50% ethyl acetate/n-hexane mixture to give the title compound as a pale yellow oil (1.57 g, 3.32 mmol, 45%).
