Versuchsvorschrift

A mixture of methyl 4-chloro-2-[(3-hydroxypropyl)amino]-3-({[6-methoxy-2-(trifluoromethyl)pyridin-3-yl]carbamothioyl}amino)benzoate (1.85 g, 3.75 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.79 g, 4.12 mmol) and triethylamine (0.57 mL, 4.16 mmol) in tetrahydrofuran (20 mL) was stirred at 50° C. for 3 hr. Water was added to the reaction mixture at room temperature and the mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with a 25-80% ethyl acetate/n-hexane gradient mixture to give the title compound (1.50 g, 3.27 mmol, 87%) as a pale yellow solid.
