Procedure

In a 10 mL round-bottomed flask fitted with a N2 inlet was placed a stir bar, 1-(2-fluoro-4-methanesulfonyl-phenyl)-4-(piperidin-4-yloxy)-1H-pyrazolo[3,4-d]pyrimidine (43 mg, 0.1 mmol), K2CO3 (138 mg, 1 mmol) and DMF (1 mL). 2-Bromo-1-(4-trifluoromethoxy-phenyl)-ethanone (30 mg, 0.1 mmol) was added in one portion. The reaction mixture was stirred at room temperature for 30 minutes. The resulting suspension was filtered and concentrated under vacuum. The crude was purified by preparative HPLC to give Compound A94. 1H NMR (CDCl3, 400 MHz) δ 2.43 (m, 2H), 2.59 (m, 2H), 3.14 (s, 3H), 3.68 (m, 2H), 3.78 (m, 2H), 4.78 (s, 2H), 5.81 (m, 1H), 7.35 (d, 2H), 7.96 (m, 3H), 8.01 (m, 2H), 8.42 (s, 1H), 8.65 (s, 1H). Exact mass calculated for C26H23F4N5O5S 593.14, found 594.3 (MH+).
