実験手順

A mixture of 4-bromo-2-fluoro-5-(trifluoromethyl)aniline (78 mg, 0.302 mmol) and [(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 (150 mg, 0.302 mmol) in toluene (0.6 mL, 6 mmol) and water (0.4 mL, 20 mmol) was purged with nitrogen. Potassium carbonate (208.8 g, 1.511 mmol) and tetrakis(triphenylphosphine)-palladium(0) (35 mg, 0.030 mmol) were added under an atmosphere of nitrogen. The reaction mixture was capped and heated at 100° C. overnight, cooled to RT, and partitioned between ethyl acetate (5.0 mL) and water (1.5 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated to give a yellowish oil, which was purified by silica gel chromatography (12 g silica gel, 0-100% EtOAc/hexanes). Desired fractions were combined and concentrated to give the title intermediate as a yellowish solid (128 mg, 77% yield). (m/z): [M+H]+ calcd for C27H24F4N5O3 548.22 found 548.6.
