To a solution of (1S,4S)-5-(6-chloro-2-methylsulfonyl-pyrimidin-4-yl)-2-oxa-5-azabicyclo[2.2.1]heptane (500 mg, 1.73 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (382 mg, 1.73 mmol), and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (II) (63.8 mg, 0.0863 mmol) in acetonitrile (6.90 mL) was added potassium acetate in water (3.45 mL) in a microwave vial equipped with a stirbar. The mixture was microwaved at 110° C. for 5 min. The solid was and washed with ethyl acetate (5 mL) filtered under vacuum, providing 6-((1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptan-5-yl)-2-(methylsulfonyl)-[4,5′-bipyrimidin]-2′-amine (598 mg, crude). 1H NMR (400 MHz, DMSO-d6) δ 9.02 (d, J=5.6, 2.8 Hz, 2H), 7.40-6.97 (m, 1H), 7.28 (s, 2H), 5.14 (d, J=16.0 Hz, 1H), 4.76 (d, J=27.9 Hz, 1H), 3.82 (d, J=7.7, 1.5 Hz, 1H), 3.76-3.66 (m, 1H), 3.60-3.51 (m, 1H), 3.50-3.41 (m, 1H), 3.35 (d, J=6.1 Hz, 3H), 1.95 (d, J=22.0 Hz, 2H).
