Reaction Steps

3-(1-(4-amino-3-(3-(benzyloxy)-5-fluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl)-4-(3-(4,4,5,5-tetramethyl-1,3-dioxolan-2-yl)phenyl)-1H-isochromen-1-one (intermediate F5, 654 mg, 0,919 mmol) was dissolved in MeCN, then 2M HCl was added and the mixture was stirred overnight. DCM (25 ml) and water (25 ml) were added then phases were separated and the aqueous phase was washed again with 10 ml of DCM. The collected organic phases were concentrated to give the title compound (490 mg, 0.801 mmol, 87% yield) as a brown oil.
