Procedure

A mixture containing N-(6-chloro-2-cyclohexylpyrimidin-4-yl)-5-fluoro-1H-pyrazolo[3,4-b]pyridin-3-amine (78 mg, 0.22 mmol), N, N-diisopropylethylamine (158 μL, 0.91 mmol), azetidine (45 μL, 0.67 mmol) and n-butanol (6 mL) was heated at 125° C. for 20 min in the microwave. The reaction mixture was cooled to room temperature and the resulting solid was filtered and the solid washed with Et2O, sNH4Cl and Et2O. The resulting solid was air dried to give the title compound as a white solid (48 mg, 58%). MS (ES+) m/e=368. 1H NMR: (DMSO) 1.08-1.92 (10H, m), 2.26-2.58 (3H, m), 3.89-4.06 (4H, m), 6.50 (1H, brs), 8.32-8.62 (2H, m), 9.79 (1H, s), 13.03 (1H, s)
