To a mixture of N-{3-[3-(2-chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]phenyl}-2,2,2-trifluoroacetamide (0.5 g, 1.2 mmol) in i-PrOH (4 mL) was added 5-(3-aminophenyl)oxazole (0.25 g, 1.56 mmol) and 2 drops of conc. HCl. The reaction was heated in a microwave to 120° C. for 40 min. and allowed to cool to rt. The resulting solid was filtered off, washed with i-PrOH and dried to give the title compound as a tan solid (0.68 g) in 98% yield. ES-LC/MS m/z=542 [M+H]+.
