Reaction Steps

Methyl (2S,3R)-1-((1R,4S)-3-(5-(4-bromo-2-fluorophenyl)-1H-imidazol-2-yl)-2-azabicyclo[2.2.1]heptan-2-yl)-3-methoxy-1-oxobutan-2-ylcarbamate (162 mg, 0.318 mmol), methyl (S)-3-methyl-1-oxo-1-((S)-2-(7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-naphtho[1,2-d]imidazol-2-yl)pyrrolidin-1-yl)butan-2-ylcarbamate (199 mg, 0.382 mmol), Pd(PPh3)4 (37 mg, 0.0318 mmol) and K2CO3 (2M in H2O, 0.4 mL, 0.8 mmol) were suspended in DME (3 mL). The reaction mixture was degassed with N2 for 11 min then heated to reflux for 2.5 h. Upon completion, the reaction mixture was diluted with MeOH, filtered over a thiol SPE column and concentrated. The crude residue was purified by silica column chromatography (0% to 50% MeOH/EtOAc) to afford the title compound (125 mg, 48%). (ESI) m/z 823 [M+H]+.
