実験手順

4-(4-aminophenylazo)-phenylamine (3.02 g) and pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester (7.00 g) were dissolved in DCM (90 mL), and 1-ethoxycarbonyl-1,2-dihydroquinoline (8.45 g) was added. The reaction mixture was stirred at ambient temperature for 19 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-{4-[(1-carboxylic acid tert-butyl ester-pyrrolidine-2-carbonyl)-amino]-phenylazo}-phenylcarbamoyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (9.28 g) as a brown solid.
