실험 절차

Methyl (S)-1-((1S,3S,4R)-3-(7-bromo-1H-naphtho[1,2-d]imidazol-2-yl)-2-azabicyclo[2.2.1]heptan-2-yl)-3-methyl-1-oxobutan-2-ylcarbamate (0.300 g, 0.601 mmol), (S)-tert-butyl 2-(7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-naphtho[1,2-d]imidazol-2-yl)pyrrolidine-1-carboxylate (0.334 g, 0.721 mmol), and aqueous potassium phosphate (2M, 0.901 mL, 1.802 mmol) were suspended in 1,2-dimethoxyethane (3.00 mL) and sparged with argon gas for 30 minutes. Palladium tetrakis triphenylphosphine (0.069 g, 0.060 mmol) was added and the reaction mixture was capped and placed in a preheated 80° C. oil bath. The solution was heated for 18 hours and subsequently stirred at room temperature for two days. Upon completion, the reaction was diluted with ethyl acetate and washed with brine. The concentrated organic layer was purified by normal phase chromatography (40-100% ethyl acetate (10% MeOH) in hexanes) to give (S)-tert-butyl 2-(2′-((1S,3S,4R)-2-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-2-azabicyclo[2.2.1]heptan-3-yl)-1H,1′H-7,7′-binaphtho[1,2-d]imidazol-2-yl)pyrrolidine-1-carboxylate (0.305 g, 67%). LCMS-ESI+: calc'd for C44H49N7O5: 755.38 (M+); Found: 756.8 (M+H+).
