Participants

Reaction Steps

To N-(3-aminopropyl)-2-(4-carbamoylphenyl)amino)-4-(propylamino)pyrimidine-5-carboxamide (D3) trifluoroacetate (100 mg), N-Boc-N-methyl-L-alanine (47 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (128 mg) and 1-hydroxybenzotriazole monohydrate (102 mg), N,N-dimethylformamide (2 mL) and triethylamine (116 μL) were added at room temperature, and the mixture was stirred at the same temperature for 1 hour. To the reaction mixture, water and ethyl acetate were added. The organic layer was separated, washed successively with water and saturated aqueous sodium chloride, and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to obtain (S)-tert-butyl (1-((3-(2-((4-carbamoylphenyl)amino)-4-(propylamino)pyrimidine-5-carboxamido)propyl)amino)-1-oxopropan-2-yl)(methyl)carbamate (D4, 103 mg) as white solid.
