3-(1-Bromoethyl)-4-(6-methylpyridin-3-yl)-1H-isochromen-1-one hydrobromide (intermediate C10, 120 mg, 0.282 mmol), 1H-pyrazolo[3,4-d]pyrimidin-4-amine (76 mg, 0.565 mmol), and K2CO3 (117 mg, 0.847 mmol) were stirred in DMF (1.5 ml) at 50° C. for 2.5 hrs. The reaction mixture was diluted with 1M HClaqueous (2 ml) and purified via reverse phase chromatography with a Biotage C18 SNAP column (Phase A, water 95%, ACN 5%, formic acid 0.1%); Phase B ACN 95%, water 5%, formic acid 0.1%) to give the title compound as colourless solid (16.7 mg, 15%).
