Methanol → 3-{4-[3-(2-fluoro-5-trifluoromethyl-phenyl)ureido]phenyl}-1-methyl-1H-indole-2-carboxamide

Participants

Reaction Steps

0.075 g of 2-fluoro-5-trifluoromethylphenyl isocyanate is added to a solution of 0.086 g of 1-methyl-3-(4-aminophenyl)-1H-indole-2-carboxamide in 18 ml of tetrahydrofuran and the stirring is continued for 1 hour. 5 ml of methanol are added, the reaction mixture is then concentrated under reduced pressure, and the residue is purified by chromatography on a silica column, elution being carried out with a mixture of cyclohexane and ethyl acetate (20/80 by volume), to give 90 mg of 3-{4-[3-(2-fluoro-5-trifluoromethyl-phenyl)ureido]phenyl}-1-methyl-1H-indole-2-carboxamide, the characteristics of which are as follows:
