Versuchsvorschrift

To a solution of 1-(2-fluorobenzyl)-N-(1H-pyrazol-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-amine (56 mg, 0.18 mmol), (Example 88), in DCM (2 mL) were added triethylamine (384, 1.5 eq) and acetyl chloride (154, 1.2 eq). After stirring for 30 min at rt, the reaction mixture was quenched with water. The aqueous phase was extracted with DCM and the combined organic phases dried over sodium sulfate and concentrated in vacuo. The residue was purified with the preparative HPLC to give the title product. 1H NMR (d6-DMSO) δ 10.25 (s, 1H), 9.03 (s, 1H), 8.67 (s, 1H), 8.15 (s, 1H), 8.04 (s, 1H), 7.41-7.31 (m, 2H), 7.26-7.12 (m, 2H), 5.60 (s, 2H), 2.63 (s, 3H); LC-MS method B, (ES+) 352.0, RT=9.09 min.
