Reaction Steps
To a solution of methyl (S)-1-((2S,4S)-2-(5-(6-bromonaphthalen-2-yl)-1H-imidazol-2-yl)-4-hydroxypyrrolidin-1-yl)-3-methyl-1-oxobutan-2-ylcarbamate (100 mg, 0.19 mmol) in DME (2 mL) was added (S)-tert-butyl 2-(5-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (83 mg, 0.19 mmol), Pd(PPh3)4 (22 mg, 0.019 mmol), and K2CO3 (2M in H2O, 0.32 mL, 0.63 mmol). The solution was degassed with N2 for 10 min, then heated to 85° C. for 18 h. The mixture was cooled to rt, diluted with EtOAc, and washed with sat. NaHCO3, brine, dried over MgSO4, and concentrated. The residue was purified by silica gel chromatography to yield product (61 mg).
