Versuchsvorschrift

Methyl (S)-3-methyl-1-oxo-1-((S)-2-(5-(3-(prop-1-ynyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-1H-imidazol-2-yl)pyrrolidin-1-yl)butan-2-ylcarbamate (153 mg, 0.28 mmol), (2S,4S)-tert-butyl 2-(7-bromo-1H-naphtho[1,2-d]imidazol-2-yl)-4-(methoxymethyl)pyrrolidine-1-carboxylate (158 mg, 0.34 mmol), Pd(PPh3)4 (32 mg, 0.028 mmol), Pd(dppf)2Cl2 (20 mg, 0.028 mmol), and K2CO3 (2M in H2O, 0.46 mL, 0.92 mmoL) were combined in DME (4 mL). The mixture was degassed with bubbling N2 for 10 min the heated to 85° C. for 16 h. After cooling, the reaction mixture was diluted with EtOAc, and washed successively with saturated aqueous NaHCO3 and brine. The organics were dried over MgSO4, filtered and concentrated under reduced pressure. The crude residue was purified by silica column chromatography (0% to 30% MeOH/EtOAc) to afford (2S,4S)-tert-butyl 2-(7-(4-(2-((S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)pyrrolidin-2-yl)-1H-imidazol-5-yl)-2-(prop-1-ynyl)phenyl)-1H-naphtho[1,2-d]imidazol-2-yl)-4-(methoxymethyl)pyrrolidine-1-carboxylate (66 mg, 30%).
