Procedure

In a 50 mL round-bottomed flask was placed 1-(2-fluoro-4-methanesulfonyl-phenyl)-4-(piperidin-4-yloxy)-1H-pyrazolo[3,4-d]pyrimidine (300 mg, 0.7 mmol) and triethylamine (584 μl). DMF (6 mL) was added to completely dissolve the solid material. The reaction flask was immersed in an ice-bath. Trifluoromethoxybenzoyl chloride (180 mg, 0.8 mmol) was added to the solution and the mixture was stirred 2 h under N2 at 0° C. After all of the starting amine was completely converted as indicated by LCMS, the reaction was stopped by quenching with water. The reaction mixture was then concentrated under vacuum and purified by preparative HPLC. 1H NMR (CDCl3, 400 MHz) δ 1.98 (m, 1H), 2.12 (m, 2H), 2.27 (m, 1H), 3.13 (s, 3H), 3.51 (m, 1H), 3.79 (m, 2H), 4.21 (m, 1H), 5.76 (m, 1H), 7.31 (d, 2H), 7.52 (d, 2H), 7.95 (m, 3H), 8.36 (s, 1H), 8.65 (s, 1H). Exact mass calculated for C25H21F4N5O5S 579.12, found 580.2 (MH+).
