| titleOfInvention | Method for producing 4,5,6,7-tetrahydrothieno [3,2-c] pyridine-2-carboxylic acid derivative |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a 4,5,6,7-tetrahydrothieno [3,2-c] pyridine-2-carboxylic acid derivative in which the reaction time is short and the generated acidic waste liquid is reduced. Offer. SOLUTION: A diazonium salt of 5-acetyl-3-amino-4,5,6,7-tetrahydrothieno [3,2-c] pyridine-2-carboxylic acid n-butyl ester is prepared by adding water to ethyl acetate. By reducing with hypophosphorous acid in the presence of copper powder in a mixed solvent, 5-acetyl-3-amino-4,5,6,7-tetrahydrothieno [3,2-c] pyridine-2- The carboxylic acid n-butyl ester is obtained. |
