Reaction Steps

A mixture of 1-(4-fluorophenyl)-5-isopropyl-pyrazol-4-amine (0.070 g, 0.32 mmol), 3-[2-methyl-4-(trifluoromethyl)imidazol-1-yl]tetrahydrofuran-2-one (0.070 g, 0.30 mmol) and AlMe3 (0.50 mL, 1.0 mmol, 2 M/toluene) was heated at 55° C. for 1.5 hrs. The mixture was then cooled to room temperature, diluted with aqueous ammonium hydroxide, and extracted with EtOAc. The organic layer was separated, dried over anhydrous sodium sulfate, concentrated in vacuo, and purified by flash chromatography (SiO2, 0˜20% MeOH/CH2Cl2 gradient elution) to give 3-[[1-(4-fluorophenyl)-5-isopropylpyrazol-4-yl]amino]-3-[2-methyl-4-(trifluoromethyl)imidazol-1-yl]propan-1-ol (0.030 g, 24%).
