40 mg (0,094 mmol) of 4-[3-(3-aminophenyl)-1-(4-methoxybenzyl)-1H-pyrazol-4-yl]-N-tert-butylpyridin-2-amine were dissolved in 2 ml of dry dimethylformamide and 12 μL (0.094 mmol) of p-trifluoromethylphenylisocyanate were added. The solution was stirred at room temperature for 3 hours. The reaction mixture was then poured into water and the product extracted several times with ethylacetate. The organic layer was dried over Na2SO4 and evaporated to dryness. The crude was purified by chromatography on a silica gel column eluted with dichloromethane-acetone 9/1, affording 40 mg (70% yield) of the title compound.
