Vorschrift

To a solution of 80 mg 1H-Benzoimidazole-2-carboxylic acid in 1 mL DMF and 0.2 mL NEt3, 200 mg 1-Pyrimidin-4-yl-piperidin-4-ylamine trifluoroacetate and 125 mg BOP-Cl were added and the mixture was stirred for 3 h. Finally, 3 mL saturated NaHCO3 solution were added and the mixture was filtered through a chem elut® cartridge by elution with ethyl acetate. After removal of the solvent under reduced pressure the crude product was subjected to the next reaction step without further purification. Yield: 160 mg.
