실험 절차

A mixture of methyl (S)-3-methyl-1-oxo-1-((1R,3S,4S)-3-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-2-yl)-2-azabicyclo[2.2.1]heptan-2-yl)butan-2-ylcarbamate (122 mg, 0.25 mmol), (S)-tert-butyl 2-(5-(7-bromo-9,9-difluoro-9H-fluoren-2-yl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (127 mg, 0.25 mmol), 1M aqueous sodium bicarbonate solution (0.93 mL, 0.93 mmol), triphenylphosphine (13 mg, 0.05 mmol), palladium(II) acetate (5.5 mg, 0.02 mmol) and dimethoxyethane (2.5 mL) was degassed with a stream of argon for twenty minutes. The reaction was heated to 95° C. After four hours, the reaction was cooled to room temperature and diluted with ethyl acetate. The organic phase was washed with saturated aqueous NaHCO3 solution and brine, dried (Na2SO4) and concentrated. The crude material was purified by flash column chromatography to yield (S)-tert-butyl 2-(5-(9,9-difluoro-7-(2-((1R,3S,4S)-2-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-2-azabicyclo[2.2.1]heptan-3-yl)-1H-benzo[d]imidazol-6-yl)-9H-fluoren-2-yl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (106 mg, 54%).
