1-Fluoro-3-isocyanato-5-(trifluoromethyl)benzene → 2-acetylamino-4-{4-[3-(3-fluoro-5-trifluoromethylphenyl)ureido]phenyl}-1H-pyrrole-3-carboxamide

참여 물질

반응 단계

0.061 cm3 (0.426 mmol) of 3-fluoro-5-trifluoromethylphenyl isocyanate is added at room temperature to a suspension of 100 mg (0.387 mmol) of 2-acetylamino-4-(4-aminophenyl)-1H-pyrrole-3-carboxamide in 5 cm3 of anhydrous tetrahydrofuran. The reaction medium is stirred at room temperature for 24 hours, cooled in a water-ice bath and then filtered on sintered glass. The solid collected is washed with a small amount of dichloromethane and cyclohexane and then dried under vacuum. 75 mg of 2-acetylamino-4-{4-[3-(3-fluoro-5-trifluoromethylphenyl)ureido]phenyl}-1H-pyrrole-3-carboxamide are obtained in the form of a beige solid.
