Reaction Steps

Methyl (S)-2-((S)-2-(7-bromo-4,5-dihydro-1H-naphtho[1,2-d]imidazol-2-yl)pyrrolidin-1-yl)-2-oxo-1-(tetrahydro-2H-pyran-4-yl)ethylcarbamate (211 mg, 0.408 mmol), (S)-tert-butyl 2-(5-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)naphthalen-2-yl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (220 mg, 0.449 mmol), Pd(PPh3)4 (47 mg, 0.0408 mmol) and K2CO3 (2M in H2O, 0.45 mL, 0.9 mmol) were suspended in DME (4 mL). The reaction mixture was degassed for 10 min with N2 then heated to 85° C. After 17 h, it was cooled to RT, diluted with MeOH, filtered over a thiol SPE column and concentrated. The crude residue was purified by silica column chromatography (0% to 40% MeOH/EtOAc) to afford the title compound (130 mg, 40%).
