To a solution of 5-(2-(2-azabicyclo[2.1.1]hexan-2-yl)-6-((1S,4S)-2,5-diazabicyclo[2.2.1]heptan-2-yl)pyrimidin-4-yl)-3-(trifluoromethyl)pyridin-2-amine (80 mg, 0.22 mmol) in DMSO (2 mL) was added acetic anhydride (46 mg, 0.44 mmol) and N-ethyl-N-isopropylpropan-2-amine (0.1 mL). The mixture was stirred at room temperature for 25 min. The mixture was concentrated in vacuum and the residue was purified by Prep-HPLC (BASE) to provide 1-((1S,4S)-5-(6-(6-amino-5-(trifluoromethyl)pyridin-3-yl)-2-(2-azabicyclo[2.1.1]hexan-2-yl)pyrimidin-4-yl)-2,5-diazabicyclo[2.2.1]heptan-2-yl)ethanone (46.34 mg, 40.0% yield). LCMS (ESI): [MH]+=459.9; 1H NMR (400 MHz, DMSO-d6) δ 8.91 (s, 1H), 8.36 (s, 1H), 6.79 (s, 2H), 6.53-6.21 (m, 1H), 5.10-4.89 (m, 1H), 4.80-4.78 (m, 1H), 4.74-4.63 (m, 1H), 3.55-3.51 (m, 1H), 3.44-3.35 (m, 2H), 3.23-2.84 (m, 4H), 2.82 (s, 1H), 2.00 (s, 1H), 1.91 (s, 3H), 1.83-1.81 (m, 2H), 1.29 (d, J=2.0 Hz, 2H).
