Procedure

75 mg potassium-tert-butoxide are added at ambient temperature under an argon atmosphere to 225 mg N-(5-tert-butyl-3-methanesulphonylamino-2-methoxy-phenyl)-3-hydroxy-4-methyl-benzamide in 3 ml N,N-dimethylformamide. After ten minutes 210 mg tert-butyl 4-(6-chloro-pyrimidin-4-carbonyl)-piperazine-1-carboxylate are added, and the reaction mixture is stirred for six days at ambient temperature. For working up the reaction mixture is mixed with water and extracted with ethyl acetate. The combined ethyl acetate extracts are washed with saturated sodium chloride solution, dried on magnesium sulphate and evaporated down. The flask residue is chromatographed through a silica gel column with cyclohexane/ethyl acetate (50:50→20:80).
