Procedimiento

The mixture of (R)-3-bromo-N-(2,4-dimethoxybenzyl)-1-(1-tosyl-4,5,6,7-tetrahydro-1H-indazol-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (80 mg, 0.125 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-N-(4-(trifluoromethyl)pyridin-2-yl)benzamide (59 mg, 0.150 mmol), Pd(PPh3)2Cl2 (9.2 mg, 0.0125 mmol) and K2CO3 (43 mg, 0.313 mmol) in dioxane/H2O (3 mL/0.3 mL) was stirred for 2 h at 90° C. under nitrogen atmosphere. Then the mixture was added water and extracted with DCM. The combined organic layer was washed with water, brine and dried over anhydrous Na2SO4. Concentrated in vacuo and the residue was purified with silica gel chromatography with PE/EA=1/1 to give (R)-4-(4-((2,4-dimethoxybenzyl)amino)-1-(1-tosyl-4,5,6,7-tetrahydro-1H-indazol-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-N-(4-(trifluoromethyl)pyridin-2-yl)benzamide (90 mg, yield 87.2%) as yellow solid.
