実験手順

4,4′-Ethylenedianiline (2.98 g) and pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester (7.09 g) were dissolved in DCM (90 mL), and 1-ethoxycarbonyl-1,2-dihydroquinoline (8.38 g) was added. The reaction mixture was stirred at ambient temperature for 3 hours and evaporated under vacuum. Oil was dissolved in ethyl acetate, forming a precipitate, which was collected by vacuum filtration and dried under vacuum, giving 2-[4-(2-{4-[(1-carboxylic acid tert-butyl ester-pyrrolidine-2-carbonyl)-amino]-phenyl}-ethyl)-phenylcarbamoyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (8.30 g, 97%) as a white solid.
