Reaction Steps

To a solution of N-{3-[3-(2-chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]phenyl}-2,2,2-trifluoroacetamide (3.0 g, 0.007 mols) (see Example 1, Step C) in 1,4-dioxane (60 mL) and i-PrOH (60 mL) was added 3-[(dimethylamino)methyl]aniline (1.61 g, 0.011 mol) followed by catalytic 12M HCl. After heating four days at 90° C., reaction was quenched with saturated NaHCO3 (100 mL), solvent removed by rotary evaporation, aqueous layer extracted with DCM (3×200 mL), organic layers concentrated, and purified by column chromatography (0-100% 9:1:0.1 DCM:MeOH:NH4OH) to provide the product (1.25 g, 40%) as tan foam. ES-LC/MS m/z=436 [M+H]+.
