실험 절차

To a suspension of 3-{[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}-3-oxopropanoic acid (600 mg) and tert-butyl (2-aminoethyl)carbamate (240 mg) in tetrahydrofuran (12 ml) and dichloromethane (6 ml) was added WSCD HCl (522 mg), and the whole mixture was stirred at room temperature overnight. To the reaction mixture was added water (3 ml), and the whole mixture was extracted with ethyl acetate. The extract was washed with water and brine and dried over magnesium sulfate. The evaporation of the solvent gave a crude residue, which was triturated with diisopropyl ether-ethyl acetate (2:1) to give tert-butyl {2-[(3-{[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}-3-oxopropanoyl)amino]ethyl}carbamate (537 mg).
