Versuchsvorschrift

5-Bromo-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 61.1, 90 mg, 0.25 mmol), 2-methoxypyridin-3-ylboronic acid (45.9 mg, 0.300 mmol), K2CO3 (69.1 mg, 0.500 mmol), PdCl2(dppf)-(CH2Cl2) (20.42 mg, 0.025 mmol), water (0.6 mL) and dioxane (3 mL) were added to a vial, which was sealed, evacuated/purged with argon and the RM was stirred at 60° C. for 1 h. The RM was treated with water and extracted with EtOAc. The combined extracts were washed with water and brine, dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give the crude product which was purified by flash chromatography (Silica gel column, 15 g, EtOAc) to afford the title compound as a white powder.
