Paragraph 0072-0083, (2021/05/12)
The invention relates to preparation methods of a 1H-indazol-3-carboxylic acid derivative, granisetron and lonidamine. The 1H-indazol-3-carboxylic acid derivative is a compound with a structure shown in a formula (1) and a formula (2), and is mainly structurally characterized by having a 1H-indazol-3-carboxylic acid amide skeleton and a 1H-indazol-3-carboxylic ester skeleton. The 1H-indazol-3-carboxylic acid derivative can be synthesized by taking simple o-aminophenylacetic acid amide or o-aminophenylacetic acid ester as an initial raw material. The 1H-indazol-3-carboxylic acid derivative is a key intermediate for synthesizing a plurality of medicines, such as granisetron, lonidamine and the like. The synthesis method of the 1H-indazol-3-carboxylic acid derivative and the drug molecules glassetron and lonidamine is simple, the reaction condition is mild, the reaction speed is high, the yield is high, and purification is easy.
