Base) ethyoxyl] benzophenone and 1,2- diphenyl -1- [4- [2- (N, N- dimethylamino) ethyoxyl] phenyl] -1,4-butanediol
Preparation method.
Background technique
Toremifene (Toremifene) is that the estrogen receptor antagon class that Famos company, Finland develops in nineteen eighty-three is anti-
Tumour medicine, for treating postmenopausal women's estrogen receptor positive or unknown metastatic breast cancer, 1996 by Orion
Company lists in European Union, trade name Fareston.Toremifene is administered orally in the form of citric acid.Toremifene and tamoxifen
Fragrant structure is alike, the mechanism of action is similar, belongs to the antiestrogen of triaryl butylene class.In recent years the study found that citron
Sour Toremifene is the active drug for inhibiting Ebola virus.
4- [2- (N, N- dimethylamino) ethyoxyl] benzophenone (4- (2- (dimethylamino) ethoxy) phenyl)
(phenyl) methanone) and 1,2- diphenyl -1- [4- [2- (N, N- dimethylamino) ethyoxyl] phenyl] -1,4- butanediol
(1- (4- (2- (dimethylamino) ethoxy) phenyl) -1,2-diphenylbutane-1,4-diol) is citric acid support
Two important intermediates in Rui meter Fen preparation process.The synthesis of Toremifene Citrate is original with 4- dihydroxy benaophenonel
Material, with N, N- dimethylamino chloroethanes hydrochloride occurs O- alkylated reaction and generates 4- [2- (N, N- dimethylamino) ethyoxyl] two
Benzophenone, under the action of Lithium Aluminium Hydride, 4- [2- (N, N- dimethylamino) ethyoxyl] benzophenone is obtained with cortex cinnamomi aldehyde reaction
1,2- diphenyl -1- [4- [2- (N, N- dimethylamino) ethyoxyl] phenyl] -1,4-butanediol, chemical equation are as follows:
According to document (Xu Xiaoguang, the synthesis of Toremifene Citrate, Chinese Journal of Pharmaceuticals, 2002,33 (9), 417-
418 and slow general et al., the optimization of synthesis of Toremifene Citrate, contemporary Chinese medicinal application, 2013,7 (12), 236-
237) report, 4- [2- (N, N- dimethylamino) ethyoxyl] synthesis of benzophenone are auxiliary with water using acetone as solvent
Solvent, some have also used phase transfer catalyst tetrabutylammonium chloride.It, can be fixed even if reacting with the synthesis technology of acetone as solvent
Amount is completed, but the self-condensation of unavoidable acetone under alkaline condition, condensation product and 4- [2- (N, N- dimethylamino) ethoxy
Base] benzophenone separation difficulty will lead to 4- [2- (N, N- dimethylamino) ethyoxyl] benzophenone purity decline.1,2-
General use is post-processed in diphenyl -1- [4- [2- (N, N- dimethylamino) ethyoxyl] phenyl] -1,4-butanediol preparation process
Water or aqueous ammonium chloride solution destroy unreacted Lithium Aluminium Hydride, then the routine operations such as layering.Due to ether solvent water solubility compared with
Greatly, causing a large amount of solvents and portioned product to bring water phase into causes yield to reduce, and also causes water pollution, the drawbacks such as cumbersome.
" Heilungkiang medical science " ((Zhang Ruiren etc., 2012,35 (4), 29-30)) report " Toremifene Citrate
Intermediate improvement in synthesis " method, propose using cinnamyl alcohol directly with 4- [2- (N, N- dimethylamino) ethyoxyl] hexichol first
Ketone reacts in tetrahydrofuran, prepares 1,2- diphenyl -1- [4- [2- (N, N- dimethylamino) ethoxy with medium yield
Base] phenyl] -1,4-butanediol method.It theoretically derives, since this method reacts front and back valent state non-conservation, the party
Method cannot prepare Toremifene Citrate intermediate;And it is verified through actual tests, this method cannot equally prepare citron
Sour Toremifene intermediate 1,2- diphenyl -1- [4- [2- (N, N- dimethylamino) ethyoxyl] phenyl] -1,4-butanediol.
