To a 15 mL capacity reaction tube was added 2-(cyclopropylmethylamino)-5-(3-fluoro-4-(1-(4-methoxybenzyl)-3-methyl-1H-pyrazolo[3,4-b]pyridin-4-yloxy)phenyl)-3-methylpyrimidin-4(3H)-one (23.8 mg, 0.044 mmol) and the solids were dissolved in TFA (0.5 mL, excess). The reaction mixture was stirred at 80° C. for 1 hour in a sealed tube. The excess solvent was evaporated and the crude residue was purified by silica gel chromatography (Biotage 12M) loading with EtOAc and eluting with 3% MeOH/EtOAc to give the title compound as pink solid (8.5 mg, 46%).
