To a solution of (S)—N-(1-(6-chloro-3-(4-chloro-1-methyl-3-(methylsulfonamido)-1H-indazol-7-yl)pyridin-2-yl)-2-(3,5-difluorophenyl)ethyl)-2,2,2-trifluoroacetamide (57D, 870 mg, 1.40 mmol) in EtOH (16 mL) was added 2M aqueous LiOH (7.0 mL, 13.98 mmol). The reaction was heated in a microwave reactor at 130° C. for 10 minutes. Upon cooling, the reaction mixture was acidified with 2N aqueous HCl until at pH 5. The reaction mixture was then concentrated in vacuo and taken in EtOAc. To the solution was added saturated aqueous NaHCO3 until the aqueous layer was at pH 10. The organic layer was collected, and the aqueous layer was extracted an additional time with EtOAc. The combined organic layers were dried over Na2SO4, filtered, concentrated in vacuo, and used without further purification. MS (m/z) 526.06 [M+H]+.
