Versuchsvorschrift

A mixture of methyl 4-chloro-3-{[(2,6-dichloro-4-methoxyphenyl)carbamothioyl]amino}-2-[(3-hydroxypropyl)amino]benzoate (255 mg, 0.517 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (109 mg, 0.569 mmol) and triethylamine (0.0793 mL, 0.569 mmol) in tetrahydrofuran (5 mL) was stirred at 50° C. for 2 hr. The reaction mixture was diluted with ethyl acetate, washed with water and brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel eluting with a 30-70% ethyl acetate/n-hexane gradient mixture to give the title compound as a colorless solid (215 mg, 0.469 mmol, 91%).
