Procedure
Lithium hydroxide, monohydrate (13 mg, 0.31 mmol) was added to a solution of methyl 3′-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5′-chloro-3-fluoro-2′-methoxy-6′-methylbiphenyl-4-carboxylate made above (0.030 g, 0.062 mmol) in methanol (0.2 mL)/tetrahydrofuran (0.2 mL)/water (0.09 mL). The reaction was stirred at room temperature for 1.5 h, then treated with conc. HCl (60 uL) to adjust pH to 2, The solvent was removed to provide the crude product which was used in next step without further purification. LCMS calculated for C23H22ClFN5O3 (M+H)+: m/z=470.1; Found: 470.2
