In a 16 mL reaction vial was placed sodium hydride (48 mg, 60% in oil, 1.2 mmol) and 5 mL of THF. (3-Fluoro-phenyl)-(4-hydroxy-piperidin-1-yl)-methanone (66 mg, 0.3 mmol) was added to the suspension and the mixture was stirred 60 min under N2 at room temperature, followed by the addition of 4-chloro-1-(4-methanesulfonyl-phenyl)-1H-pyrazolo[3,4-d]pyrimidine (60 mg, 0.2 mmol). After stir another 2 hrs under N2 at room temperature, all of the starting chloropyrozolepyrimidines was completely converted as indicated by LCMS. The reaction mixture was then filtered through a syringe filter and purified HPLC to give Compound A8. 1H NMR (CDCl3,400 MHz) δ 1.95 (m, 2H), 2.21 (m, 2H), 3.11 (s, 3H), 3.45 (m, 1H), 3.68 (m, 1H), 3.75 (m, 1H), 4.20 (s, 1H), 5.72 (m, 1H), 7.12 (m, 1H), 7.16 (m, 1H), 7.22 (m, 1H), 7.41 (m, 1H), 8.11 (d, 2H), 8.27 (s, 1H), 8.62 (d, 2H), 8.67 (s, 1H). Exact mass calculated for C24H22FN5O4S 495.14, found 496.3 (MH+)
