Procedure

To a solution of N-{5-[3-(2-chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]-2-fluorophenyl}-2,6-difluorobenzamide (162 mg, 0.34 mmol) in 1,4-dioxane (6 mL) and 2-propanol (2 mL) was added 7-amino-N-trifluoroacetyl tetrahydroisoquinoline (165 mg, 0.68 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), organic layer concentrated, and purified by column chromatography (5-50% EtOAc in hexanes) to provide the product (109 mg, 47%) as an off-white solid. ESIMS (M+H)+=688.
