Reaction Steps

0.3 mmol of 3-quinoline boronic acid (Aldrich, Buchs, Switzerland), 8 mg of bis(triphenylphosphine)palladium (II) dichloride (Fluka, Buchs, Switzerland) and 0.5 ml of a 1 M solution of Na2CO3 are added to a solution of 84 mg (0.2 mmol) of 2-[4-(8-bromo-3-methyl-2-oxo-2,3-dihydro-imidazo[4,5-c]quinolin-1-yl)-phenyl]-2-methyl-propionitrile (Example 1i) in 2 ml of DMF. The mixture is stirred for 1 h. at 100° C. After this time, the mixture is quenched with sat. aqueous NaHCO3 and extracted with EtOAc (2×). The organic layer is washed with brine, dried over Na2SO4, filtered and evaporated in vacuo. The residue is loaded on silica gel and purified by flash chromatography to give the title compound. ES-MS: 470 (M+H)+; analytical HPLC: tret=2.90 min (Grad 1).
