Reaktionsschritte

To a flask with methyl 3-(5,5-dimethylcyclopent-1-enyl)-4-(trifluoromethylsulfonyloxy)benzoate T3.5 (404 mg, 1068 μmol) was added Pd(PPh3)4 (123 mg, 107 μmol), potassium carbonate (443 mg, 3203 μmol), 5-fluoro-2-methoxypyridin-4-ylboronic acid T19.1 (456 mg, 2669 μmol, commercially available from Asymchem). The mixture was then degassed, and DMF (3 mL) was added. The reaction was stirred overnight at 87° C. and worked up with EtOAc and water. Silica gel chromatography (0-50% EtOAc/Hexanes) afforded methyl 3-(5,5-dimethylcyclopent-1-enyl)-4-(5-fluoro-2-methoxypyridin-4-yl)benzoate T19.2 (295 mg. 78%).
