| Abstract：5-Aminosalicylic acids was one of the preferred drugs in clinical, so it had important significance to investigate the process of its preparation. Firstly three main methods of synthesizing 5-Aminosalicylic acids such as nitro reduction, Kolbe, azobenzolsalicylic acid intermediate reduction methods were reviewed in this paper. Next their relative merits were compared in point of reaction conditions, yield and environmental protection. Finally the development and prospect of 5-Aminosalicylic acids were put f... |
