Procedure

0.048 g (1.19 mmol) of sodium hydride is added at 0° C. to 0.200 g (0.598 mmol) of 1-tert-butyl-5-(3,5-difluorophenylthio)-1H-pyrazolo[3,4-b]pyridin-3-amine dissolved in 10 ml of anhydrous dimethylacetamide. The reaction is left under stirring for 10 minutes. 0.130 g (0.598 mmol) of 1-(4-isocyanatophenyl)-4-methylpiperazine is then added at 0° C. The mixture is left under stirring for 3 hours at room temperature. The reaction is treated by adding 20 ml of water drop by drop at 0° C. and then is extracted with ethyl acetate. The organic phase is dried on sodium sulfate, filtered and concentrated. The product is purified by silica chromatography to yield 0.150 g (yield=45%) of 1-(1-tert-butyl-5-(3,5-difluorophenylthio)-1H-pyrazolo[3,4-b]pyridin-3-yl)-3-(4-(4-methylpiperazin-1-yl)phenyl)urea in the form of a light brown solid.
