Beschreibung

2-Methylindazole-3-carboxylic acid is a potential impurity in the synthesis of granisetron. It is a byproduct of the reaction between methyl iodide and indazole, which is an unreacted material in the synthesis of 2-methylindazole-3-carboxylic acid. The hydrochloride salt form of granisetron can be obtained by reacting granisetron with hydrochloric acid or hydrogen chloride gas in presence of a base such as triethylamine. 2-Methylindazole-3-carboxylic acid may also be recycled from the reaction mixture. In addition, this compound has been found to be present in low yield in a pharmacopeia for granisetron hydrochloride tablets.
