Versuchsvorschrift

5-Bromo-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 61.1, 181 mg, 0.5 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (133 mg, 0.6 mmol), PdCl2(dppf)-(CH2Cl2) (20.42 mg, 0.025 mmol), K2CO3 (138 mg, 1 mmol), water (2 mL) and dioxane (10 mL) were added to a vial, which was sealed, evacuated/purged with argon and the RM was stirred at 90° C. for 24 h. The solvent was evaporated off under reduced pressure and the residue was treated with water and extracted with EtOAc. The combined extracts were dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give the product which was recrystallized from hot EtOAc to afford the title compound as a beige powder. UPLC-MS (Condition 2) tR 0.89 min, m/z=376.2 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 6.98 (s, 2H) 7.41 (d, J=8.99 Hz, 2H) 7.90 (d, J=8.99 Hz, 2H) 8.50-8.55 (m, 1H) 8.76 (s, 2H) 9.00 (d, J=1.95 Hz, 1H) 9.06 (d, J=1.96 Hz, 1H) 10.62 (s, 1H).
