Diisopropylethylamine → N-(1-benzylpyrrolidin-3-yl)-4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)pyrimidine-5-carboxamide

Participants

Reaction Steps

To a solution of 4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)pyrimidine-5-carboxylic acid (A3, 90 mg) in N,N-dimethylformamide (2 mL), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (63 mg) and 1-hydroxybenzotriazole monohydrate (45 mg) were added at room temperature, and the mixture was stirred at the same temperature for 2 hours and 30 minutes. To the reaction mixture, N,N-diisopropylethylamine (153 μL) and 1-benzyl-3-aminopyrrolidine (53 mg) were added at room temperature, and the mixture was stirred at the same temperature for 2 hours. To the reaction mixture, water was added. The solid matter was taken by filtration, washed with water, and then dried under reduced pressure. The obtained solid matter was purified by basic silica gel column chromatography to obtain N-(1-benzylpyrrolidin-3-yl)-4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)pyrimidine-5-carboxamide (E9, 117 mg).
