Reaction Steps

N-{3-[3-(2-Chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]phenyl}-2-(2-thienyl)acetamide (109 mg, 0.25 mmol) (see Example 2, step B) and N-(5-amino-2,3-dihydro-1H-inden-2-yl)-2,2,2-trifluoroacetamide (72 mg, 0.30 mmol) were combined in i-PrOH (2 mL) and 1M hydrochloric acid in diethyl ether (25 μL, 0.025 mmol) and heated at 180° C. in the microwave reactor for 20 min. The reaction product was concentrated and purified directly by silica gel flash column chromatography (30-100% EtOAc in hexanes). Purification yielded 61 mg (38%) of a brown oil. ES-LC/MS m/z=654 [M+H]+.
