Procedure

To a solution of N-[5-[3-(2-chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]-2-(methyloxy)phenyl]-2,6-difluorobenzamide (158 mg, 0.32 mmol) in 1,4-dioxane (6 mL) and 2-propanol (2 mL) was added 7-amino-N-trifluoroacetyl tetrahydroisoquinoline (158 mg, 0.64 mmol) followed by catalytic 12M HCl. After heating overnight at 80° C., reaction was quenched with saturated NaHCO3 (25 mL), solvent removed by rotary evaporation, aqueous layer extracted with DCM (25 mL), the organic layer was concentrated and purified by column chromatography (5-50% EtOAc in hexanes) to provide the product (100 mg, 44%) as an off-white solid. ESIMS (M+H)+=700.
