Procedure

In a 50 mL round-bottomed flask equipped with a N2 inlet septum was placed a stir bar, NaH (60% in mineral oil, 364 mg, 0.91 mmol) and 5′-isopropoxy-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-ol (215 mg, 0.91 mmol). THF (anhydrous, 3 mL) was added to the mixture. The resulting suspension was stirred about 30 min at room temperature. 4-Chloro-1-(2-fluoro-4-methanesulfonyl-phenyl)-1H-pyrazolo[3,4-d]pyrimidine (297 mg, 0.91 mmol) was then added in one portion. The mixture was stirred overnight under N2 at room temperature and the resulting slurry turned slightly yellowish. The slurry was added CH2Cl2 and filtered. The filtrate was concentrated under vacuum to give the crude product. Purification by preparative HPLC gave the desired product as an off-white solid. 1H NMR (CDCl3, 400 MHz) δ 1.36 (d, 6H), 2.17 (m, 2H), 2.30 (m, 2H), 3.13 (s, 3H), 3.74 (m, 2H), 3.97 (m, 2H), 4.50 (m, 1H), 5.76 (m, 1H), 7.04 (d, 1H), 7.60 (m, 1H), 7.87 (m, 1H), 7.94 (m, 3H), 8.34 (s, 1H), 8.64 (s, 1H). Exact mass calculated for C26H28FN5O4S 525.18, found 526.2 (MH+)
