{3-[3-(2-Chloro-4-pyrimidinyl)-6-methylpyrazolo[1,5-a]pyridin-2-yl]phenyl}amine (0.57 g, 1.68 mmol) and 2-thienylacetyl chloride (0.25 mL, 2.00 mmol) were stirred in THF (30 mL) and stirred for 16 h. Additional 2-thienylacetyl chloride was added until reaction was complete by LC/MS. The mixture was concentrated to dryness and partitioned between aqueous NaHCO3 (saturated) and DCM. The organic layers were concentrated and purified by column chromatography to afford N-{3-[3-(2-chloro-4-pyrimidinyl)-6-methylpyrazolo[1,5-a]pyridin-2-yl]phenyl}-2-(2-thienyl)acetamide as a yellow solid (0.69 g, 89%). ES-LC/MS m/z=460 [M+H]+.
