Procedure

To a stirred solution of (E)-N-(3-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)phenyl)-4-(cyclobutyl(methyl)amino)-N-methylbut-2-enamide (52) (222 mg, 0.4 mmol) and 2-(3-methoxy-4-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (119 mg, 0.48 mmol) in DMF/H2O (4 mL/1 mL) were added Pd(dppf)Cl2 (16 mg, 0.02 mmol) and K3PO4.3H2O (320 mg, 1.2 mmol). The resulting mixture was purged with N2 (3×) and stirred at 80° C. overnight. Solvents were removed in vacuo. The residue was pre-purified by flash chromatography (silica gel, 0 to 10% MeOH in DCM with 0.3% TEA) followed by a prep HPLC to provide (E)-N-(3-(4-amino-3-(3-methoxy-4-methylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)phenyl)-4-(cyclobutyl(methyl)amino)-N-methylbut-2-enamide (53) (29 mg, 14%) as a white solid.
