"Process for the preparation of indolecarboxylic acid hydrazides", such as indolyl-carbonyl-hydrazines and indolyl-alkyl-carbonyl-hydrazines, which is characterized, by reaction of the ethyl or ethyl esters of indole acids, with hydrazine hydrate, an appropriate solvent medium, such as methanol, ethanol or isopropanol and heating this reaction mixture for a variable time, at a temperature between 40º C and reflux. To obtain the pure product, the solvent is removed and recrystallized from ethanol, methanol, isopropanol or dimethylformamide. (Machine-translation by Google Translate, not legally binding)
