Tetrakis(triphenylphosphine)palladium(0) (17.4 mg, 0.015 mmol) was added to a solution of 2,6-dichloro-1,5-naphthyridine (30 mg, 0.151 mmol), sodium bicarbonate (38.0 mg, 0.452 mmol) and (1R,3S,5R)-tert-butyl 3-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-2-yl)-2-azabicyclo[3.1.0]hexane-2-carboxylate (141 mg, 0.332 mmol) in dioxane (1.0 mL) and H2O (0.2 mL) and the mixture was heated and stirred at 110° C. for 2 h. The reaction was diluted with MeOH, filtered, concentrated and purified by prep HPLC (H2O-MeOH with 10 mM NH4OAc buffer) to yield tert-butyl (1R,3S,5R)-3-(5-(6-(2-((1R,3S,5R)-2-(tert-butoxycarbonyl)-2-azabicyclo[3.1.0]hex-3-yl)-1H-benzimidazol-6-yl)-1,5-naphthyridin-2-yl)-1H-benzimidazol-2-yl)-2-azabicyclo[3.1.0]hexane-2-carboxylate (22.3 mg, 0.030 mmol) as a white solid. LC-MS retention time 2.11 min; m/z 725 [M+H]+. (Column PHENOMENEX® Luna 3.0×50 mm S10. Solvent A=90% water: 10% methanol: 0.1% TFA. Solvent B=10% water: 90% methanol: 0.1% TFA. Flow Rate=4 mL/min. Start % B=0. Final % B=100. Gradient Time=3 min. Wavelength=220).
