1) Eight kinds of aminovinyl compounds were prepared by the condensation of various diphenyl or dipyridyl formamidines to the respective quaternary salts of quinaldine, 6-diethylaminoquinaldine, and 4-ethylpyridine. By the application of p-acetaminobenzene sulfochloride to several of the aminovinyl compounds, some compounds containing p-acetaminobenzenesulfamino group were obtained.
2) By the application of p-dimethylaminobenzaldehyde or p-dimethylaminocinnamic aldehyde to 6-chloro (nitro, dimethylamino, diethylamino)-quinaldines, 2, 3, 5, 6-tetramethylpyrazine, 4-nitro-2, 6-lutidine-N-oxide, quinaldine-N-oxide and 2, 3, 5, 6-tetramethyl-pyrazine-N, N′-dioxide, corresponding p-dimethylaminostyryl and p-dimethylaminocin-namylidenemethyl compounds were obtained.
