실험 절차

350 mg (0.82 mmol) of 4-[3-(3-aminophenyl)-1-(4-methoxybenzyl)-1H-pyrazol-4-yl]-N-tert-butyl-pyridin-2-amine were dissolved in 30 ml of dry dimethylformamide and 110 μl (0.82 mmol) of p-trifluoromethyl-phenyl isocyanate were added to the resulting solution. The mixture was stirred overnight at room temperature, then poured into an aqueous solution of sodium hydrogenocarbonate and extracted with dichloromethane. The organic phase was dried over sodium sulphate and evaporated in vacuo. The residue was chromatographed on a silica gel column (dichloromethane-acetone 9/1), affording 302 mg (60%) of the title compound.
