Reaction Steps

To a microwave vial charged with (1S,4S)-5-(2-(2-azabicyclo[2.1.1]hexan-2-yl)-6-chloropyridin-4-yl)-2-oxa-5-azabicyclo[2.2.1]heptane (70 mg, 0.24 mmol), 3-(difluoromethoxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-amine (75.53 mg, 0.26 mmol) and potassium carbonate (66.29 mg, 0.48 mmol) in dioxane/water (5:1, 3.0 mL) was added 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride (3.5 mg, 0.048 mmol) under nitrogen. The vial was sealed and heated by microwave irradiation at 120° C. for 1 h. The reaction mixture was concentrated in vacuo, and resulting residue was purified by PR-HPLC (Basic) to afford 5-[6-(3-azabicyclo[2.1.1]hexan-3-yl)-4-[(1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptan-5-yl]-2-pyridyl]-3-(difluoromethoxy)pyridin-2-amine (24.55 mg, 24.6% yield).
