Procedure

A mixture of 5-[3-(2-chloro-4-pyrimidinyl)imidazo[1,2-a]pyridin-2-yl]-N-(2,6-difluorophenyl)-2-(methyloxy)benzamide (Intermediate Example 2) (0.60 g, 1.22 mmol), 5-ethyl-2-(methyloxy)-4-{4-[4-(methylsulfonyl)-1-piperazinyl]-1-piperidinyl}aniline (Example 206, Step B) (0.48 g, 1.22 mmol) and HCl (4N,1,4-Dioxane, 0.61 mL, 2.44 mmol) in trifluoroethanol (15 mL) was heated at 170° C. for 40 min in the microwave. The reaction mixture was concentrated onto silica gel and purified by flash column chromatography. Recrystallization from DCM and EtOH afforded the title compound N-(2,6-difluorophenyl)-5-(3-{2-[(5-ethyl-2-(methyloxy)-4-{4-[4-(methylsulfonyl)-1-piperazinyl]-1-piperidinyl}phenyl)amino]-4-pyrimidinyl}imidazo[1,2-a]pyridin-2-yl)-2-(methyloxy)benzamide (0.61 g, 56%).
