Reaction Steps

A flask is charged with 4-{[4-(4-bromophenyl)pyrimidin-2-yl]amino}benzenesulfonamide (0.681 g, 1.68 mmol), tert-butyl(dimethyl){[(2E)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)prop-2-en-1-yl]oxy}silane (1.00 g, 3.35 mmol), (Ph3)4Pd (0.194 g, 0.168 mmol), potassium carbonate (0.695 g, 5.03 mmol), ethanol (3.0 ml), water (3.0 ml), and toluene (25 ml). The reaction mixture is stirred at 85° C. for 4 h. The reaction mixture is cooled to room temperature, and trifluoroacetic acid (1.0 ml) is added. The reaction mixture is then stirred for 16 h at room temperature. The reaction mixture is concentrated and purified on preparative HPLC to yield 0.196 g of a yellow solid. MS (ESI) m/z 383.2; HRMS: calcd for C19H18N4O3S+H+, 383.11724; found (ESI-FTMS, [M+H]1+), 383.11752.
