Procedimiento

LiOH (2M solution, 2 drops) was added into a solution of 3-(4-(2-fluoro-4-(1-(4-fluorophenyl)-6-oxo-1,6-dihydropyridazine-5-carboxamido)phenoxy)-1H-pyrazolo[3,4-b]pyridin-3-ylamino)cyclohexyl 2,2,2-trifluoroacetate (10 mg, 0.015 mmol, obtained from Example 131, Step C) in THF (0.5 mL) and MeOH (0.1 mL). HCl (5M, 0.1 mL). EtOAc was added to dilute the reaction mixture. The organic layer was separated, washed with brine, dried with Na2SO4, filtered and concentrated to afford the product (2.5 mg, 29% yield) as a yellow solid.
