Reaction Steps

To the mixture of 6-((1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptan-5-yl)-2-(methylsulfonyl)-[4,5′-bipyrimidin]-2′-amine (380 mg, 1.09 mmol) and potassium carbonate (754 mg, 5.45 mmol) in DMSO (5 mL) was added 2-azabicyclo[2.1.1]hexane hydrochloride (326 mg, 2.73 mmol). The mixture was stirred at 100° C. for 5 h. After removal of the solvent, the residue was purified by Prep-HPLC (formic acid) to afford 2-(2-azabicyclo[2.1.1]hexan-2-yl)-6-((1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptan-5-yl)-[4,5′-bipyrimidin]-2′-amine (220 mg, 57% yield). LCMS (ESI): [MH]+=352.1; 1H NMR (400 MHz, DMSO-d6) δ 8.91 (s, 2H), 7.00 (s, 2H), 6.30-6.10 (m, 1H), 5.10-4.90 (m, 1H), 4.83 (d, J=6.4 Hz, 1H), 4.70-4.64 (m, 1H), 3.78-3.76 (m, 1H), 3.66-3.64 (m, 1H), 3.45-3.38 (m, 4H), 2.89-2.87 (m, 1H), 1.93-1.86 (m, 4H), 1.32-1.31 (m, 2H).
