Abstract
Treatment of N-benzoyl derivative of n-dianisylhydroxyethyl amine with HCl results in benzoyl transition to benzoate and, at the same time, dehydration occurs to give β-p-nitrobenzoylamino di-p-methoxystilbene as a by-product. Deamination of normal base gives n-hydro-anisoine. Dipiperonylhydroxyethylamine, obtained by treatment of tyrosine and glycine by piperonal under the presence of alcoholic potash solution and subsequent hydrolysis, seems to be iso-compound from the results of its de-amination and benzoyl transition. Iso-hydroxypiperoine, obtained by de-amination coincides with the substance obtained by Fittig-Reusen.
