Ethyl 5-Hydroxy-2-methyl-1-(pyridin-2-ylmethyl)benzo[g]indole-3-carboxylate

Indole ring is widely represented in natural compounds, as well as in a great variety of drugs. In this paper, the synthesis of a 5-hydroxybenzoindole derivative carrying a pyridyl substituent on position 1 is reported. The method involved no chromatography for purification and used solvents and catalysts of very low toxicity.
