66981-73-5 Usage
Chemical Properties
White Solid
Originator
Stablon,Servier,France,1983
Uses
Tianeptine is used in the treatment of reactive and neurotic depression, as well as in the treatment of anxious states.
Uses
Tricyclic compound with psychostimulant, anti-ulcer and anti-emetic properties. Antidepressant
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.

Paragraph 0043-0046, (2020/10/05)
The present invention relates to a method for preparing 3,11-dichloro-6-methyl-6,11-dihydrodibenzo[c,f][1,2]thiazepine 5,5-dioxide. More particularly, 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.
Synthesis method of tianeptine sodium
-
Paragraph 0011, (2020/03/06)
The invention relates to a synthesis process of a drug tianeptine sodium, particularly to a method for synthesizing tianeptine sodium by using 3-chloro-6-methyldibenzo[c,f][1,2]thiazepine-11(6H)-keto-5,5-dioxide as a starting material through Schiff base forming with an amine, reducing, hydrolyzing, and freeze-drying and salt forming. According to the invention, the method is stable in starting material, easy to purchase and simple in process; and the synthesis route is mild in overall reaction condition, simple in experimental operation and easy to realize industrial production.
