To an ice-cooled solution of (1S,4S)-tert-butyl 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]heptane-2-carboxylate (130 mg, 0.25 mmol) in dichloromethane (6 mL) was added trifluoroacetic acid (3 mL). The mixture was stirred at room temperature for 0.5 h. After removal of the solvent, the residue was dissolved with water (30 mL), basified and extracted with dichloromethane (3×30 mL). The organic layer was dried over sodium sulfate, concentrated to provide 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, 75.0% yield). LCMS (ESI): [MH]+=417.9.
