Reaction Steps

37 mg (0.3 mmol) of 4-pyridineboronic 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 (CH2Cl2-MeOH 97:3 to 18:1) to give the title compound as an off-white solid. ES-MS: 420 (M+H)+; analytical HPLC: tret=2.40 min (Grad 1).
