Versuchsvorschrift

150 mg (1.00 mmol) 4,6-dichloropyrimidine, 367 mg (1.50 mmol) 4-benzyloxy-3,5-dimethylbenzaldehyde and 166 mg (0.600 mmol) 1,3-dimethyl-3H-benzimidazol-1-ium-iodide (Chem. Pharm. Bull. 1990, 1147-52) in 10.0 mL THF were stirred at RT. Then 73.0 mg (1.51 mmol) sodium hydride (50% in mineral oil) were added and the reaction mixture was refluxed for 2.5 h. The reaction mixture was added to ice water and extracted with DCM. The organic phase was dried and evaporated down.
