(2S,4S)-tert-butyl 4-hydroxy-2-(5-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (200 mg, 0.44 mmol) and methyl (S)-1-((S)-2-(5-(6-bromonaphthalen-2-yl)-1H-imidazol-2-yl)pyrrolidin-1-yl)-3-methyl-1-oxobutan-2-ylcarbamate (219 mg, 0.44 mmol) were combined in DME (5 mL). Pd(PPh3)4 (51 mg, 0.0446 mmol) and K2CO3 (2M H2O, 0.73 mL, 1.45 mmol) were added, and the solution was degassed with N2 for 10 min. The solution was heated to 85° C. and stirred o/n. The following morning, the solution was cooled to rt. The solution was diluted with EtOAc, washed with sat. NaHCO3, brine, dried over MgSO4, and concentrated. The residue was purified by silica gel chromatography to yield product (36 mg).
