Reaction Steps

A mixture of 3-((trimethylsilyl)ethynyl)imidazo[1,2-a]pyridin-8-yl trifluoromethanesulfonate (0.329 g, 0.91 mmol), 0.186 (1.09 mmol) of 4-(methylsulfonyl)aniline, 0.083 g (0.091 mmol) of Pd2(dba)2, 0.087 g (0.181 mmol) of 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl, and 0.385 g (1.81 mmol) of potassium phosphate in 8 mL of DME was heated at 80° C. in a sealed tube overnight under an atmosphere of N2. Upon cooling to ambient temperature, the reaction mixture was concentrated and the crude product was purified by silica gel flash chromatography (triethylamine-treated silica gel; eluted with 0-80% EtOAc/hexanes) to provide 0.058 g of product: 384 m/z (M+H).
