To a microwave vial charged with (1S,4S)-5-(6-chloro-2-(methylsulfonyl)pyrimidin-4-yl)-2-oxa-5-azabicyclo[2.2.1]-heptane (600 mg, 2.07 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (641 mg, 2.90 mmol), potassium acetate (284 mg, 2.90 mmol) and sodium carbonate (307 mg, 2.90 mmol) in acetonitrile/water (1 (5:1, 6.0 mL) was added PdCl2{PtBu2(Ph-p-NMe2)}2 (147 mg, 0.21 mmol) under nitrogen. The vial was sealed and heated by microwave irradiation at 140° C. for 40 min. The reaction mixture was concentrated in vacuo, and resulting residue was purified by flash column chromatography (5% methanol in dichloromethane) to provide 6-((1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptan-5-yl)-2-(methylsulfonyl)-[4,5′-bipyrimidin]-2′-amine (380 mg, 52.7% yield). LCMS (ESI): [MH]+=349.0.
