Methyl 3-amino-4-chloro-2-((3-hydroxypropyl)amino]benzoate → Methyl 4-chloro-2-[(3-hydroxypropyl)amino]-3-({[6-methoxy-2-(trifluoromethyl)pyridin-3-yl]carbamothioyl}amino)benzoate

Participants

Reaction Steps

A solution of methyl 3-amino-4-chloro-2-[(3-hydroxypropyl)amino]benzoate (1.00 g, 3.87 mmol) and 3-isothiocyanato-6-methoxy-2-(trifluoromethyl)pyridine (1.81 g, 7.73 mmol) in tetrahydrofuran (10 mL) was stirred at room temperature for 3 days. The reaction mixture was concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with a 30-100% ethyl acetate/n-hexane gradient mixture to give the title compound (1.85 g, 3.75 mmol, 97%) as a pale red amorphous.
