实验步骤: A stirred mixture of 157 parts of N-(3-dimethylaminopropyl)formamide in 20.0 parts of water was heated to 80° C. and over a period of one and one half hours there was added 171 parts of N-ethyl-N-(2-chloroethyl)aniline. The reaction mixture was heated at 95°-100° C. until a small sample when diluted with water gave a clear solution. After about seven hours of heating at 95°-100° C. there was obtained N,N-dimethyl-N-2-(N'-ethylanilino)ethyl-N-3-formamidopropylammonium chloride in the form of an aqueous solution. The reaction mixture was heated at 95°-100° C. until a small sample when gave a clear solution After about seven hours of heating at 95°-100° C.

实验步骤: Proceeding in a manner similar to that described above in B-8a, 29.9 parts of N-(3-dimethylaminopropyl)formamide and 44.3 parts of 5-nitro-1-chloromethylnaphthalene were interacted in 30 parts of water to obtain N,N-dimethyl-N-(5-nitro-1-naphthylmethyl)-N-3-formamidopropylammonium chloride. The product was not isolated but was used directly in solution for reduction of the nitro group.

实验步骤: To a stirred solution of 143.5 parts of N-(3-dimethylaminopropyl)formamide and 700 parts of water is added 249 parts of p-acetamidophenacyl chloride. The mixture is stirred at room temperature for 16 hours and then at 60°-65° C. for 2 hours. Insoluble material is removed by filtration. The filtrate is combined with one-half its volume of concentrated hydrochloric acid (36% by weight) and the resulting solution is heated at the boil for 2 hours. The aqueous solution of N,N-dimethyl-N-(p-aminophenacyl)-N-3-aminopropylammonium chloride is used as such in the preparation of dyes. at 60°-65° C. for 2 hours Insoluble material is removed by filtration the resulting solution is heated at the boil for 2 hours such in the preparation of dyes
