摘 要: | 1. α,ω-Bis- (p-alkoxyphenylamino) -alkanes, N,N'-bis-(p-substituted phenyl)- alkane dicarboxamides and N, N'-bis-(p-substituted phenyl)-alkane dicarboxylates were prepared for studying the relationship between chemical structure and thera- peutic activity, against Schistosomiasis japonica in experimental animals. 2. α,ω-Bis-(p-alkoxyphenylamino)-heptanes were prepared from p-alkoxyaniline and 1,7-dibromoheptane in the presence of sodium bicarbonate. α,ω-Bis-(p-alkoxy- phenylamino)-pentanes were prepared by hydrolysis of N,N'-bis-(p-alkoxyphenyl)- N, N'-bis-(p-toluene sulfonyl)-pentanediamines with 25% hydrochloric acid, while the latter were obtained by condensation of N-(p-alkoxyphenyl)-p-toluene sulfonamides with 1,5-dibromopentane in alcoholic alkaline solution. 3. N, N'-Bis-(p-substituted phenyl)-alkane dicarboxamides were prepared from p-substituted aniline and alkane dicarboxylic acid chlorides. According to Grimmel's method, we also prepared these compounds of this series by the reaction of p,p'-bis- (dimethylamino)-phosphazo benzene with corresponding alkane dicarboxylic acid. In the case of succinic acid, we obtained, however, mainly N-(p-dimethylaminophenyl)- succinimide instead of succinic diamide. 4. The intermediate, p-diethylamino-ethoxyaniline, was prepared by hydrolysis of the condensation product of p-acetaminophenol and diethylaminoethyl chloride. 5. Sodium salt of dimethylaminophenol was treated with alkane dicarboxylic acid chloride to give the corresponding N, N'-bis-(p-dimethylaminophenyl) -alkane dicar- boxylates.
