Reaction Steps
A solution of 1.72 g of 6-(4-aminophenyl)-3-[(thiophen-3-yl)carbonylamino]-1H-indazole hydrochloride and 0.65 mL of triethylamine in 70 mL of tetrahydrofuran is admixed slowly under an argon atmosphere with 0.67 mL of 2-fluoro-5-trifluoromethylphenyl isocyanate. The reaction mixture is stirred at 24° C. for 3.5 hours and then concentrated under reduced pressure. The residue is purified by flash chromatography on a silica column (60; 35-70 μM), eluting with a dichloromethane/methanol (97/3 by volume) mixture, to give 0.4 g of 1-(4-{3-[(thiophen-3-yl)carbonylamino]-1H-indazol-6-yl}phenyl)-3-(2-fluoro-5-trifluoromethylphenyl)urea, whose characteristics are as follows:
