Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4,4′-ethylenedianiline; 4,4′-diamino-3,3′-dimethyldiphenylmethane; 3,3′,5,5′-tetramethylbenzidine; 4,4′-diaminodiphenyl sulfone; 4,4′-diaminodiphenyl ether; 1,5-diaminonaphthalene; 3,3′-dimethyl-4,4′-diaminobiphenyl;

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4,4′-ethylenedianiline; 4,4′-diamino-3,3′-dimethyldiphenylmethane; 3,3′,5,5′-tetramethylbenzidine; 4,4′-diaminodiphenyl sulfone; 4,4′-diaminodiphenyl ether; 1,5-diaminonaphthalene; 3,3′-dimethyl-4,4′-diaminobiphenyl;

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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. evaporated under vacuum Oil was dissolved in ethyl acetate forming a precipitate, which was collected by vacuum filtration dried under vacuum
