The efficient preparation method of quetiapine fumarate comprises the following steps: the dibenzo [ b, f ] [1,4] thiazepine-11- [10H ] ketone and 1- [2 (2-hydroxy ethoxy) ethyl ] piperazine are subjected to catalytic reaction in a solvent through a copper catalyst for 6-16 hours at 80-120 ℃ to obtain quetiapine free alkali, and after separation, fumaric acid is added to form salt to obtain quetiapine fumarate; the copper catalyst includes a copper compound and an oxidizing agent.
Description
Technical Field
The invention belongs to the technical field of organic synthesis, and particularly relates to a high-efficiency preparation method of quetiapine fumarate.
Background
Quetiapine fumarate is a new generation of atypical psychosis, first marketed in the united kingdom by Zeneca corporation in 1997, month 11, and clinically used as a first line drug for schizophrenia. Quetiapine fumarate is known as 11- [4- [2- (2-hydroxyethoxy) ethyl ] -1-piperazinyl ] dibenzo [ b, f ] [1,4] thiazepine hemi-fumarate and is prepared by salifying quetiapine with fumaric acid and has the following chemical structural formula:
the literature reports that a number of synthetic routes can be made:
1. european patent EP282236 reports that dibenzo [ b, f ] [1,4] thiazepin-11- (10H) ketone is chlorinated with phosphorus oxychloride and then condensed with piperazine to obtain an intermediate 11-piperazinyl-dibenzo [ b, f ] [1,4] thiazepin, and finally condensed with 2-chloroethoxyethanol and salified with fumaric acid to obtain quetiapine fumarate. The chlorination reaction in the route is a typical dangerous reaction, and phosphorus oxychloride (the use amount is 148 mole times of dibenzo [ b, f ] [1,4] thiazepin-11- (10H) ketone) is used in a large amount, so that a large amount of phosphorus-containing wastewater is generated, and great pressure is caused to environmental management; in addition, the yield is relatively low due to the longer procedure.
2. The route reported in EP240228 is likewise dibenzo [ b, f ] [1,4] thiazepin-11- (10H) one and phosphorus oxychloride are chlorinated to give the intermediate 11-chloro-dibenzo [ b, f ] [1,4] thiazepin, which, unlike the route of EP282236, is condensed directly with the side chain 1- (2-hydroxyethoxy) ethylpiperazine to give quetiapine, the steps being reduced to a certain extent, but the overall route being still longer; the route also requires chlorination reaction and a large amount of phosphorus oxychloride; the ether and the methylene dichloride which are extremely flammable and explosive low-boiling solvents are used in the route, so that the potential safety hazard in production is high.
3. The route reported in patent W02005014590 is that dibenzo [ b, f ] [1,4] thiazepin-11- (10H) ketone is chlorinated to give intermediate 11-chloro-dibenzo [ b, f ] [1,4] thiazepin. Condensing the intermediate with 1- (2-hydroxy) ethylpiperazine to obtain 11- [4- (2-hydroxyethyl) -1-piperazinyl ] dibenzo [ b, f ] [1,4] thiazepine, condensing with a chloroethanol compound with protected hydroxy and removing the protecting group under acidic condition to obtain quetiapine, wherein the route step is longer due to the need of removing the protecting group, and the total yield is reduced; the traditional chlorination reagent is still adopted in the route, so that dangerous chlorination reaction is carried out; the mixed solvent of toluene, methanol, butanone, methanol and the like is used for multiple times in the route, so that the manufacturing cost and the environmental treatment cost are increased.
4, the route reported in patent CN101619047 is dibenzo [ b, f ] [1,4] thiazepin-11- (10H) ketone, which is chloridized by triphosgene to obtain intermediate 11-chloro-dibenzo [ b, f ] [1,4] thiazepin, which is then condensed directly with side chain 1- (2-hydroxyethoxy) ethylpiperazine to obtain quetiapine, the route is shorter than that of patent EP282236, EP240228 and W02005014590, the yield is high, triphosgene is used as chloride to carry out chloridization reaction, and no pollution is generated to environment during post treatment. However, the route still carries out chlorination reaction, and the danger of the chlorination process cannot be relieved; triphosgene is used in the route, and the compound generates phosgene after being heated, is a highly toxic product and has potential safety hazard.
In the prior art for industrially synthesizing quetiapine fumarate, at least two steps of chlorination and condensation are needed from dibenzo [ b, f ] [1,4] thiazepine-11- (10H) ketone to quetiapine fumarate, the chlorination reaction is high in risk, and certain pressure is caused to the environment after post-treatment. Based on the defects of the prior art scheme, the invention hopes to provide a high-efficiency preparation method of quetiapine fumarate.
