Reaction Steps

To a solution of 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 (251 mg, 0.48 mmol) in DME (5 mL) was added 6-bromo-2-iodobenzo[b]thiophene (82 mg, 0.24 mmol), Pd(PPh3)4 (28 mg, 0.024 mmol), and K2CO3 (2M in H2O, 0.8 mL, 1.58 mmol). The solution was degassed with N2 for 10 min, then heated to 85° C. for 24 h. The mixture was cooled to rt, diluted with EtOAc, and washed with sat. NaHCO3, brine, dried with MgSO4, and concentrated. The residue was purified by silica gel chromatography to yield product (221 mg).
