Versuchsvorschrift

4-Bromo-6-((4-chlorophenyl)(thiazol-2-yl)methyl)quinolin-2(1H)-one (80 mg, 0.185 mol, 1 equip), trans-2-(3-fluorophenyl)vinylboronic acid (61.5 mg, 0.371 mmol, 2 equip), SPhos (15.5 mg, 0.037 mmol, 0.2 equip), tripotassium phosphate (78.7 mg, 0.371 mmol, 2 equip), and palladium acetate (4.2 mg, 0.019 mmol, 0.1 equip) were added to 1,4-dioxane (5 mL) and the resulting mixture stirred for 72 h. The reaction mixture was diluted with water and ethyl acetate and the layers were separated. The organic phase was washed with saturated sodium bicarbonate, then water, dried over Na2SO4, filtered and concentrated. The residue was purified by RP-HPLC and the fractions were lyophilized. The lyophilized product was washed with hot hexanes to remove residual SPhos, filtered, and dried under vacuum to yield (E)-6-((4-chlorophenyl)(thiazol-2-yl)methyl)-4-(3-fluorostyryl)quinolin-2(1H)-one as an off-white solid.
