A solution of 6-chloro-5-methyl-3-(phenylamino)-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (75.8 mg, 0.275 mmol), trans-2-amino-cyclohexanol hydrochloride (83.4 mg, 0.55 mmol) and DIPEA (144 μL, 0.825 mmol) in DMF (3 mL) is heated at 110° C. overnight. The reaction mixture is evaporated to remove DMF under reduced pressure. The residue is then purified by chromatography to give 63.1 mg product (Yield: 64.7%). MS (ESI) m/z 355.0 [M+H]+.
