Amide arylpiperazine derivatives, their preparation method, and their application in benign prostatic hyperplasia resistance

The invention relates to ten amide arylpiperazine derivatives, their preparation method, and their use in the preparation of benign prostatic hyperplasia treatment medicines. The preparation method of the amide arylpiperazine derivatives comprises the following steps: reacting free alkali of 3-bromopropylamine hydrobromide with di-tert-butyl dicarbonate to obtain a colorless oily liquid, reacting the colorless oily liquid with o-methoxyphenylpiperazine to obtain a light yellow oily material, reacting the light yellow oily material with trifluoroacetic acid to obtain a product, and reacting the product with N,N-diisopropylethylaine, 2-(7-azobenzotriazol)-N,N,N',N'-tetramethylformamidinium hexafluorophosphate, and 5-indoleacetic acid or 3-indoleacetic acid or 3-indolepropionic acid or 3-indolebutyric acid or 5-hydroxy-2-indoleacetic acid or 5-methoxy-2-indoleacetic acid or 1-methyl-3-indoleacetic acid or 6-bromo-2-indoleacetic acid or 5-chloro-2-indoleacetic acid or 7-nitro-2-indoleacetic acid to obtain final products. Experiments prove that the benign prostatic hyperplasia resistance activities of eight compounds in the amide arylpiperazine derivatives are stronger than a contrast drug prazosin.
