Synthesis of N-alkyl/aralkyl derivatives of indole-3-aldehydes using TEBAC as phase transfer catalyst was written by Dubey, P. K.;Babu, Balaji;Narayana, M. Venkata. And the article was included in Indian Journal of Heterocyclic Chemistry in 2006.Quality Control of 5-Bromo-1-methyl-1H-indole-3-carbaldehyde This article mentions the following:
A simple and convenient procedure for the preparation of N-substituted derivatives of indoles and indole-3-aldehydes, in the presence of K2CO3 as a base and TEBAC as a phase transfer catalyst in acetonitrile medium at room temp is described. In the experiment, the researchers used many compounds, for example, 5-Bromo-1-methyl-1H-indole-3-carbaldehyde (cas: 10102-94-0Quality Control of 5-Bromo-1-methyl-1H-indole-3-carbaldehyde).
5-Bromo-1-methyl-1H-indole-3-carbaldehyde (cas: 10102-94-0) belongs to indole derivatives. Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. More than 200 indole derivatives have already been marketed as drugs or are under advanced stages of clinical trials.Quality Control of 5-Bromo-1-methyl-1H-indole-3-carbaldehyde
