実験手順

To a sealed tube were added 2-bromo-4-(5-chloropyridin-3-yl)-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridine-6-carbonitrile (Preparative Example 3.1) (0.010 g, 0.045 mmol), 2-fluoroaniline (0.0050 g, 0.045 mmol), Cs2CO3 (0.022 g, 0.067 mmol), chloro[(4,5-bis(diphenylphosphino)-9,9-dimethylxanthene)-2-(2′-amino-1,1′-biphenyl)]palladium(11) (0.0050 g, 0.0056 mmol), and dioxane (0.5 mL). The reaction vessel was purged with argon, sealed and warmed to 75° C. for 8 hours with stirring. The reaction was cooled and diluted with dioxane (1.0 mL) and was passed through a syringe filter. The collected eluent was concentrated in vacuo to afford 4-(5-chloropyridin-3-yl)-2-((2-fluorophenyl)amino)-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridine-6-carbonitrile as a crude residue. MS ESI calc'd. for C26H24ClFN6 [M+H]+ 475. found 475.
