Tianeptine/Tianeptine Acid 66981-73-5 Usage

Tianeptine is a drug used primarily in the treatment of major depressive disorder and has been studied in the treatment of irritable bowel syndrome (IBS). It increases serotonin (5-hydroxytryptamine; 5-HT) uptake in the brain (in contrast with most antidepressant agents) and reduces stress-induced atrophy of neuronal dendrites. Tianeptine is used in the treatment of reactive and neurotic depression, as well as in the treatment of anxious states. Tianeptine Acid Powder is an anxiolytic compound, primarily used for its mood boosting and anti-anxiety properties. When used in high amounts, online users report an opioid like euphoric effect. Tianeptine is a new tricyclic antidepressant which is metabolized mainly by beta-oxidation of its heptanoic side chain.

 

Manufacturing Process

A solution of 27.6 g (0.16 mol) of freshly distilled ethyl 7-aminoheptanoate in 40 ml of nitromethane was added all at once and with mechanical stirring to a suspension of 26.2 g (0.08 mol) of 5,8-dichloro-10-dioxo-11- methyldibenzo[c,f]thiazepine(1,2) in 120 ml of nitromethane. The whole was heated to 55°C for 30 minutes, the solvent was then evaporated in vacuo and the residue was taken up in water. The crude ester was extracted with ether. After evaporation of the ether 36 g of crude ester were obtained, and 30 g (0.065 mol) there of were treated under reflux with a solution of 2.8 g (0.07 mol) of sodium hydroxide in 35 ml of ethanol and 25 ml of water. After one hour's refluxing, the alcohol was evaporated in vacuo. The residue was taken up in 150 ml of water. The mixture was twice extracted with 75 ml of chloroform and the aqueous phase was evaporated in vacuo. The sodium salt was then dissolved in 150 ml of chloroform, the solution was dried over sodium sulfate and the product precipitated with anhydrous ether. The salt was filtered off, washed with ether and dried at 50°C. 13 g of sodium 7-[8-chloro-10-dioxo-11-methyldibenzo[c,f]thiazepin-(1,2)-aminoheptanoate,melting with decomposition at about 180°C, were obtained.

A process for preparing 3,11-Dichloro-6-methyl -6,11-dihydrodibenzo[c,f][1,2]thiazepine 5,5-dioxide

-

Paragraph 0043-0046, (2020/10/05)

The present invention relates to a method for preparing high-purity 3,11-dichloro-6-methyl-6,11-dihydrodibenzo[c,f][1,2]thiazepine 5,5-dioxide at a high yield under safe atmosphere through a quantitative reaction without introduction of an excessive amount of hydrogen chloride gas from the outside by substituting the hydroxyl group of 3-chloro-6-methyl-6,11-dihydrodibenzo[c,f][1,2]thiazepine-11-ol 5,5-dioxide as a starting material with a chloride group by means of hydrogen chloride gas generated in situ under the environment of acetyl chloride and the same equivalent of alcohol.
