"Process for the preparation of hydrazides of hydroxy- and alkoxy-indole carboxylic acids", such as 6-benzyloxy-indole-2-carbohydrazide, 6-methoxy-indole-2-carbohydrate and 6-hydroxy-indole-2-carbohydrazide which is characterized because the compounds are obtained by reaction of the respective ethyl or methyl esters with hydrazine hydrate in an appropriate solvent, such as methanol, ethanol, dioxane, N, N-dimethylformamide or mixtures of both and at room temperature and reflux. The products are isolated from the reaction mixture by crystallization, either directly or after dilution with water. (Machine-translation by Google Translate, not legally binding)
