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 cloride. The mixture is stirred at room temperature for 16 l 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 two hours. The aqueous solution of N,N-dimethyl-N-(p-aminophenacyl)-N-3-aminopropylammonium chloride is used as such in the preparation of dyes.
