Procedure

N-(8-bromo-1-(4-(2-cyanopropan-2-yl)phenyl)-3-methyl-1H-imidazo[4,5-c]quinolin-2(3H)-ylidene)cyanamide (2.463 mmol), bis(pinacolato)diboron (1.347 mmol), potassium acetate (2.246 mmol) and (1,1-bis(diphenylphosphino)ferrocene)-dichloropalladium (II) complex with DCM (50 mg) was dissolved in dioxane under argon atmosphere. The reaction mixture was refluxed for 8 h. The reaction mixture was cooled, diluted with ethyl acetate (15 mL) and filtered. The filtrate was concentrated. The crude product was purified (silica gel column ethyl acetate/petroleum ether) to obtain the title compound. 1HNMR (300 MHz, DMSO-d6): δ 9.17 (s, 1H), 8.05 (m, 4H), 7.86 (m, 6H), 7.26 (s, 1H), 3.88 (s, 3H), 1.78 (s, 6H); MS (m/z): 411(M+1)+.
