Versuchsvorschrift

A mixture of [(S)-2-methyl-1-((S)-2-{4-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-propyl]-carbamic acid methyl ester (253 mg, 0.52 mmol) and the TFA salt of (R)-4-[5-(4-bromo-3-ethoxy-phenylcarbamoyl)-pyridin-2-yl]-3-methyl-piperazine-1-carboxylic acid tert-butyl ester (324 mg, 0.52 mmol; Preparation 21) was dissolved in 1,2-dimethoxyethane (5.32 mL, 51.2 mmol) and water (0.92 mL, 51.2 mmol) and the mixture was sparged under nitrogen. Sodium bicarbonate (161 mg, 1.92 mmol) was added, followed by tetrakis(triphenylphosphine)palladium(0) (89 mg, 0.077 mmol). The reaction mixture was further sparged with nitrogen, sealed under nitrogen and heated at 90° C. overnight. The reaction mixture was extracted with ethyl acetate and water. The organic layer was dried over sodium sulfate, filtered and concentrated to produce the title intermediate as a brown oil. (m/z): [M+H]+ calcd for C44H56N8O7 809.43 found 809.6.
