Versuchsvorschrift

To 4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)pyrimidine-5-carboxylic acid (A3, 452 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (575 mg) and 1-hydroxybenzotriazole monohydrate (405 mg), N,N-dimethylformamide (10 mL) was added at room temperature, and the mixture was stirred at 40° C. for 2 hours. The reaction mixture was cooled to room temperature, then N,N-diisopropylethylamine (765 μL) and N-Boc-1,3-propanediamine (330 mg) were added to the mixture, and the mixture was stirred at the same temperature for 2 hours. To the reaction mixture, saturated aqueous sodium hydrogencarbonate and ethyl acetate were added. The organic layer was separated, washed successively with water and saturated aqueous sodium chloride, and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (eluent, 100 to 95% ethyl acetate in methanol) to obtain tert-butyl (3-(4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)pyrimidine-5-carboxamido)propyl)carbamate (B3, 481 mg) as white solid.
