Versuchsvorschrift

A solution of 4-(6-chloro-2-(4-fluoro-1H-indol-2-yl)pyridin-3-yl)but-3-en-1-ol (500 mg, 1.58 mmol), (2-(4-fluorophenyl)-3-(methylcarbamoyl)-6-(N-methylmethyl sulfonamido)benzofuran-5-yl)boronic acid (800 mg, 1.89 mmol) and Na2CO3 (340 mg, 3.15 mmol) in dioxane/DMF/H2O (5 mL/1 mL/0.2 mL) was added Pd2(dba)3 (10 mg) and X-Phos (10 mg) under N2. It was put into a pre-heated oil-bath at 110° C. for 8 hours. The mixture was concentrated and it was extracted with EtOAc. The combined organic phase was washed with brine, and dried over Na2SO4. The crude product was purified by column (PE:EA=1:1) to give the pure product of (Z and E)-5-(6-(4-fluoro-1H-indol-2-yl)-5-(4-hydroxybut-1-en-1-yl)pyridin-2-yl)-2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (570 mg, yield: 52%).
