Versuchsvorschrift
57 mg (0.26 mmol) 7-methyl-2-(trifluoromethyl)-1H-benzo[d]imidazol-5-ol and 46 mg (0.30 mmol) 4,6-dichloropyrimidine were placed in 2.0 mL DMF. 0.11 g (0.78 mmol) potassium carbonate were added and the mixture was stirred overnight at 70° C. The reaction mixture was combined with ice water. The substance was extracted with ethyl acetate and evaporated down i.vac. The crude product was purified by chromatography. The fractions containing product were combined and i evaporated down.vac. to leave the aqueous residue. This was neutralised with an aqueous 4M NaOH solution and extracted with ethyl acetate. The organic phase was evaporated down i.vac.
