実験手順

1 g (2.7 mmol) of 4-[3-(3-aminophenyl)-1-(4-methoxybenzyl)-1H-pyrazol-4-yl]-pyrimidin-2-amine was dissolved in 290 ml of dry dimethylformamide and 386 μl of p-trifluoromethyl-phenylisocyanate were added. The reaction was then stirred at room temperature overnight. The mixture was poured into aqueous sodium hydrogenocarbonate and extracted with dichloromethane. The organic layer was then dried over sodium sulphate and evaporated. The crude was purified by flash-chromatography on a silica gel column (CH2Cl2-CH3COCH3; from 9/1 to 8/2), affording 800 mg (53%) of the title compound.
