Reaction Steps

The title compound was prepared by heating N-{3-[3-(2-chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]phenyl}-2,6-difluorobenzamide (180 mg, 0.39 mmol) (prepared according to a procedure similar to that described in Example 27, Step C), 3-(4-methyl-1,3-oxazol-5-yl)aniline (75 mg, 0.43 mmol), hydrochloric acid (40 μL, 0.040 mmol, 1M HCl/Et2O) and isopropanol (2 mL) at 160° C. for 15 min in a microwave synthesizer. The reaction was cooled and concentrated and purified by silica gel column chromatography (20-100% gradient EtOAc (0.5% TEA)/hexanes (0.5% TEA)). Purification yielded 60 mg (25%) of a yellow powder. ESIMS (M+H)+=601.17.
