Preparation of Donaxine: it can be prepared by indole, methanal and dicarboamine. And it is a condensation reaction. Firstly, cool the dicarboamine to -5 °C, and add it into glacial acetic acid. Then add indole and methanal into the dicarboamine at the temperature about 5 °C. The reaction time is 8 hours at reaction temperature of 30-40 °C. Via a series of cooling, acidification, crystallization you can get the product.

Uses of Donaxine: it is used for the production of anion-exchange resin. And it can react with acetic acid anhydride to get 3-acetoxymethyl-1-acetyl-indole. The reaction time is 45 minutes by heating. The yield is about 80%.
