実験手順

To a solution of 5-(5-amino-1-pentyn-1-yl)-2-chloro-N-propylpyrimidin-4-amine (K2, 505 mg) and N-Boc-N-methyl-L-alanine (270 mg) in N,N-dimethylformamide (5 mL), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (635 mg) and N,N-diisopropylethylamine (378 μL) were added at room temperature, and the mixture was stirred overnight at the same temperature. To the reaction mixture, saturated aqueous sodium carbonate and ethyl acetate were added. The organic layer was separated, washed with water, and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (eluent, 50% hexane/50% ethyl acetate) to obtain (S)-tert-butyl (1-((5-(2-chloro-4-(propylamino)pyrimidin-5-yl)-4-pentyn-1-yl)amino)-1-oxopropan-2-yl)(methyl)carbamate (L1, 660 mg).
