The condensation is less vigorous the higher the molecular weight of the acid and in some cases it is necessary to start the reaction by heating the mixture. [...] After 2 hours when the smell of the ester disappeared the mixture was washed with water and dried over caustic soda and the chloroform was evaporated off. [...] The introduction of a carbonyl carbamido or an oxamido group between two benzene rings in pp-diphenylenbisiminocamphor from benzidine and camphorquinone and a coparison of the resulting rotations with those of the corresponding compounds of benzidine and diaminodiphenylmethane would indicate the effect of such groups combined with interruption of conjugation.
