Description
Technical field
The present invention relates to a kind of method of producing thymoleptic, relate in particular to a kind of fertile method for Xi Ting of suitability for industrialized production thymoleptic Hydrogen bromide, relate to the fertile synthetic method for Xi Tingxin of a kind of Hydrogen bromide, belong to technical field of medicine synthesis.
Background technology
Major depressive disorder is disabling property of one mental disorder, the change that is characterized in being in a bad mood, interference work; affect sleep, study, diet and amusement; daily routines are had no interest, insomnia or hypersomnia, uneasiness; exciting; tired, guilt feeling or sense of uselessness, thinking or attention are concentrated difficulty; suicidal thought etc., but patient's symptom is incomplete same.Reaction difference based on patient to medicine, has multi-medicament can supply its selection.6 randomized clinical trials that the U.S. and other countries carry out show, fertilely compare major depressive disorder for Xi Ting and placebo and have obvious curative effects.
Hydrogen bromide is fertile for Xi Ting (vortioxetine hydrobromide), chemistry 1-[2-[(2 by name, 4-3,5-dimethylphenyl) sulfydryl] phenyl]-piperazine hydrobromide, it is the inhibitor of serotonin transporter, and its acceptor is carried out to activity adjusting, by Ling Bei (Lundbeck) and military field (Takeda) cooperative research and development, obtain U.S. FDA approval listing in September, 2013, trade(brand)name Brintellix, clinical major depressive disorder and the generalized anxiety disorder of being used for the treatment of.
The fertile chemical structural formula for Xi Ting of Hydrogen bromide is as follows:
About the preparation method of (I), according to disclosed bibliographical information, mainly can be divided into following several method:
Method one, Hydrogen bromide are irrigated and are replaced in western spit of fland WO 2003029232 patents taking N-bromo phenyl-N-protected base (pg) piperazine as starting raw material; with 2; the reaction of 4-dimethyl sulfydryl benzene obtains the fertile Xi Ting of replacing with protecting group, then obtains target compound (I) by deprotection.
The domestic nothing of the method starting raw material, and in synthetic, catalyzer is expensive, is not easy to obtain.
Method two, Hydrogen bromide are irrigated and are replaced in western spit of fland WO 2007144005 and WO 2010094285 patents taking bromobenzene propyl ether as starting raw material; react with the piperazine of monosubstituted protection; obtain the fertile Xi Ting of replacing with protecting group, then obtain target compound (I) by deprotection.
The domestic nothing of the same starting raw material of the method, and in synthetic, catalyzer is expensive, is not easy to obtain, and has many competition side reactions in simultaneous reactions.
Method three, fertile western spit of fland W0 2007144005 and W02013 102573 patents replaced of Hydrogen bromide disclose a kind of improved fertile preparation method for Xi Ting, directly by three functional compounds, under certain catalyst action, prepare fertile for Xi Ting (I) by the method for the treatment of different things alike.
The method is without protection and deprotection through piperazine, but the method does not fundamentally solve the competition side reaction of two halogens, thereby the purity of the product of real income only has 90% left and right.If so use the method, need to solve equally follow-up issues of purification, in addition, the method has been used expensive catalyzer, and cost is high, and difficult recovery increases the industrialization difficulty of the method.
Method four, Hydrogen bromide are irrigated for western spit of fland CN 103788019A and are disclosed with 2-nitro thiophenol or 2-amido thiophenol and 2,4-dimethyl halogeno-benzene is starting raw material, there is condensation reaction and generate 2-(2,4-3,5-dimethylphenyl sulfanyl) oil of mirbane or 2-(2,4-3,5-dimethylphenyl sulfanyl) aniline, 2-(2,4-3,5-dimethylphenyl sulfanyl) aniline obtains fertile for Xi Ting (I) with two (2-Y replacement) ethamine generation ring-closure reaction under alkaline condition.
Though the method is further improved, when reaction needed reduction, use a large amount of reductibility iron powders, and precious metal catalyst, complex operation, cost is high, and yield is low.
method four, fertile Xi Ting (Chinese Journal of Pharmaceuticals, 2014,45(4), 301～302 of replacing of Hydrogen bromide), taking o-fluoronitrobenzene as starting raw material, make fertile for Xi Ting (I) through 4 steps reactions.
The method has significantly and improves above, but still complex operation, and yield is low, and need of production high pressure, is unfavorable for suitability for industrialized production (Chinese Journal of Pharmaceuticals, 2014,45(4), 301～302 simultaneously).
