Reaction Steps

350 mg 4-(3-bromo-6-phenylimidazo[1,2-a]pyrimidin-7-yl)benzaldehyde (prepared as described in example 11), 5.6 mg Zn, 63.7 mg Zn(CN)2 and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium (II) dichloromethane adduct are suspended in dimethylacetamide and the mixture is heated for 45 min under microwave irradiation to 160° C. The workup is performed by diluting the mixture with water and dichlormethane, extracting the aqueous layer twice and drying the combined organic layers over Na2SO4. The compound is isolated by evaporation of the solvent and chromatography on silica gel (dichloromethane/methanol).
