Reaction Steps

N-(8-bromo-1-(6-(2-cyanopropan-2-yl)pyridin-3-yl)-3-methyl-1H-imidazo[4,5-c]quinolin-2(3H)-ylidene)cyanamide (2.463 mmol) was dissolved in 15 mL of dioxane under argon atmosphere. Bis(pinacolato)diboron (1.347 mmol), potassium acetate (2.246 mmol) and (1,1-bis(diphenylphosphino)ferrocene)-dichloropalladium (II) complex with DCM (50 mg) while stirring. The reaction mixture was refluxed for 8 h. After completion of the reaction, the reaction mixture was cooled and diluted with 15 mL ethyl acetate and filtered through celite. The filtrate was concentrated and the crude product was purified (silica gel column, ethyl acetate/petroleum ether as eluent) to obtain the title compound.
