Reaction Steps

55 mg 1-(3-chlor-pyrido[2,3-b]pyrazine-6-yl)-3-ethyl-urea (0.22 mmol), 60 mg o-toluidine (0.56 mmol), 33 mg sodium-tert.-butylate(0.33 mmol), 29 mg tris(dibenzalacetone)palladium(0) (0.03 mmol) and 78 mg 2-(dicyclohexylphosphanyl)biphenyl (0.22 mmol) were presented in 1.5 ml predried toluene in a microwave reaction vessel under nitrogen as protective gas. The reaction mass was heated in the microwave at 100° C. (100 watt) for 30 minutes. Then the volatile components were removed in vacuum and the raw product was cleaned using column chromatography on silica gel (solvent dichloromethane/methanol). A yellow solid was obtained.
