Versuchsvorschrift

N-{3-[3-(2-Chloro-4-pyrimidinyl)-6-methylpyrazolo[1,5-a]pyridin-2-yl]phenyl}-2,2,2-trifluoroacetamide (1.70 g, 3.94 mmol) and LiOH (0.50 g, 11.8 mmol) were combined in THF (30 mL) and water (5 mL) and stirred at 40° C. for 3 h. The mixture was cooled, concentrated to remove the THF, and extracted with DCM. The organic phase was concentrated to afford {3-[3-(2-chloro-4-pyrimidinyl)-6-methylpyrazolo[1,5-a]pyridin-2-yl]phenyl}amine which was carried on crude to Step C. ES-LC/MS m/z=336 [M+H]+.
