Versuchsvorschrift

A mixture of 4-(4-bromo-2-tert-butyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-5-yl)-N-(2-methoxypyridin-4-yl)pyrimidin-2-amine (100 mg, 0.19 mmol), 3-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrazin-2-amine (118 mg, 0.47 mmol, Example 18, Step 2), aqueous 2.0 M Na2CO3 solution (1 ml, 2.0 mmol), and Pd(PPh3)4 (22 mg, 0.019 mmol) in DME (2 mL) was sparged with N2 for 5 min. The reaction was sealed and heated to 100° C. for 2 h. The reaction was allowed to cool to rt, poured into EtOAc and partitioned with water. The layers were separated and the organic portion was washed with water, dried (MgSO4), and concentrated. The resulting residue was purified by flash chromatography (SiO2, 100:0-0:100, hexanes-25% MeOH in EtOAc) to afford 102 mg (69% purity) of 4-(4-(6-amino-5-methoxypyridin-3-yl)-2-tert-butyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-5-yl)-N-(2-methoxypyridin-4-yl)pyrimidin-2-amine: LCMS (m/z): 578.5 (MH+), tR=0.74 min.
