5-[2-methylsulfonyl-6-[(1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptan-5-yl]pyrimidin-4-yl]pyrimidin-2-amine (30.0 mg, 0.861 mmol), azetidine hydrochloride (24.7 mg, 0.258 mmol), potassium carbonate (71.4 mg, 0.517 mmol), and 1-methyl-2-pyrrolidinone (0.861 mL) were combined in a reaction flask and heated to 130° C. for 16 hrs. The reaction was filtered and purified by reverse phase column chromatography using a gradient of 20% to 60% acetonitrile in 0.1% ammonium hydroxide in water. The combined fractions containing product were concentrated under reduced pressure to provide 2-(azetidin-1-yl)-6-((1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptan-5-yl)-[4,5′-bipyrimidin]-2′-amine 1H NMR (400 MHz, DMSO-d6) δ 8.87 (s, 2H), 6.97 (s, 2H), 4.95 (s, 1H), 4.66 (s, 1H), 3.99 (t, J=7.5 Hz, 4H), 3.77 (dd, J=7.3, 1.5 Hz, 1H), 3.64 (d, J=7.3 Hz, 1H), 3.43 (dd, J=10.5, 1.5 Hz, 1H), 3.40-3.32 (m, 1H), 3.17 (s, 1H), 2.24 (p, J=7.5 Hz, 2H), 1.85 (s, 2H).
