| titleOfInvention | Method for producing 5-formyl-2-methoxybenzoic acid and its ester, and intermediate for producing the same |
| abstract | PROBLEM TO BE SOLVED: To produce 5-formyl-2-methoxybenzoic acid and esters, which are raw materials of N-benzyldioxothiazolidylbenzamide derivatives useful for the treatment of diabetes and hyperlipidemia, in high purity, industrially at low cost and in large quantities. To provide a highly safe production method. SOLUTION: 5-Chloromethyl-2-methoxybenzoic acid is reacted with hexamethylenetetraamine to obtain 1-[(3-carboxy-4-methoxy) phenylmethyl] hexamethylenetetraminium chloride, which is then hydrolyzed. As a result, 5-formyl-2-methoxybenzoic acid can be industrially produced with high purity and advantageously, and subsequently, esterification is carried out by a conventional method to produce high-purity 5-formyl-2-methoxybenzoic acid esters. .
