Procedure

876 μl (20 eq) of triethylamine is added to a solution of 238 mg (0.314 mmol) of (S)—N-(5-(3,5-difluorophenylthio)-1H-pyrazolo[3,4-b]pyridin-3-yl)-2-(2,2,2-trifluoro-N-(tetrahydro-2H-pyran-4-yl) acetamido)-4-(3-(2,2,2-trifluoroacetamido)pyrrolidin-1-yl)benzamide in 6 ml of methanol. The reaction medium is stirred at 65° C. for 4 hours. After returning to room temperature, 8 ml of n-butanol and 260 mg (6 eq) of potassium carbonate are added. The reaction medium is stirred at 80° C. for 24 hours. After returning to room temperature, the solvents are evaporated, water is added and the product is extracted with dichloromethane. The organic phase is washed with saturated sodium chloride solution, dried on magnesium sulfate, filtered and evaporated. The residue is purified by silica gel chromatography (8:2 dichloromethane/methanol as eluent) to yield 87 mg (yield=49%) of (S)-4-(3-aminopyrrolidin-1-yl)-N-(5-(3,5-difluorophenylthio)-1H-pyrazolo[3,4-b]pyrazine-3-yl)-2-(tetrahydro-2H-pyran-4-ylamino)benzamide in the form of a brown powder.
