Abstract
The invention discloses a preparation method of (S)-1-amino-3-chloro-2-propyl alcohol hydrochloride, comprising the following steps of: carrying out addition reaction on S-epichlorohydrin which is taken as a raw material and benzylamine, and deprotecting under the acid condition to form into salt to prepare a target product by a one-pot method. According to the method, a midbody does not need to be separated, and the product can be prepared by the one-pot method at high yield, so that the preparation method is simple in technological operation, and easier for the large-scale industrial production.
Description
Technical field
The present invention relates to a kind of preparation of compound, the specifically one kettle way of the chloro-2-propylate of (S)-1-amino-3-hydrochlorate preparation.
Background technology
Linezolid (linezolid) is the brand-new chemosynthesis antimicrobial drug of a kind of structure, the G* bacterium and the mycobacterium tuberculosis infection that are used for the treatment of anti-multi-medicament, be a kind of novel oxazolidinone class antibacterials, its novel structure, mechanism of action uniqueness, without cross resistance.Can be used for treating the microbemia that vancomycin-resistant enterococcus (VRE) causes, the microbemia that the pneumonia that methicillin-resistant staphylococcus aureus (MRSA) causes and comprehensive skin infections and penicillin resistance pneumococcus (PRSP) cause.
(S)-chloro-2-the propylate of 1-amino-3-hydrochlorate is the key intermediate of synthetic linezolid, and its operational path is the international monopoly protection at present.The present invention is raw material with the S-epoxy chloropropane, and benzylamine is auxiliary reagent.With the one kettle way preparation, simplified operating procedure simultaneously.Avoid the use of a large amount of ethanol in former technique simultaneously, reduced cost.
Summary of the invention
The objective of the invention is to develop the chloro-2-propylate of a kind of new method preparation (S)-1-amino-3-hydrochlorate.Former patent route reacts with ammoniacal liquor with the S-epoxy chloropropane, and phenyl aldehyde is protective material, after again phenyl aldehyde is dissociated, with a large amount of ethanol distillations, dewater simultaneously.This technological operation is loaded down with trivial details, and final product is difficult for crystallization, need dewater with a large amount of ethanol distillations.The present invention replaces phenyl aldehyde with benzylamine, can prepare by deprotection and salify one kettle way.
Realize that above-mentioned purpose technical scheme of the present invention is, a kind of preparation of the chloro-2-propylate of (S)-1-amino-3-hydrochlorate of improvement, described reaction be take the S-epoxy chloropropane as raw material, and benzylamine is auxiliary reagent, and ethanol and concentrated hydrochloric acid are solvent.This reaction can be used for lipid acid, fragrance and heterocyclic carboxylic acid.
This reaction comprises the following steps:
(1) take ethanol as solvent, addition reaction at room temperature occurs in S-epoxy chloropropane and benzylamine;
(2) add the concentrated hydrochloric acid back flow reaction in the reaction solution of step (1), then decompression steams solvent, obtains the chloro-2-propylate of (S)-1-amino-3-hydrochlorate.
Wherein, whether fully reaction is to determine by gas phase or high performance liquid chromatography.
The present invention compared with prior art has following beneficial effect: (1) the present invention substitutes phenyl aldehyde with benzylamine, and the gained intermediate need not separate direct one kettle way can realize deprotection and salt-forming reaction.Simplify operating procedure, effectively reduced cost, be easier to large-scale industrial production; (2) avoided the use of a large amount of ethanol, aftertreatment is only to use reaction solvent is steamed and can obtain product.
Embodiment
For ease of the understanding of technical solution of the present invention, below in conjunction with concrete embodiment, be introduced.
Operating procedure:
Add the 925gS-epoxy chloropropane in the 10L four-hole bottle, 2L ethanol, the cooling lower control temperature of ice-water bath is higher than 15 degree, drips the 1070g benzylamine, after stirring at normal temperature 4h.After the HPLC detection reaction, add the 5L concentrated hydrochloric acid, temperature rising reflux reaction 10h.Ethanol and part moisture are removed in distillation, stop distillation when the residual solvent amount is 3L in bottle.Be cooled to 0 degree, separate out white solid.Use cold washing with alcohol, drying, obtain the chloro-2-propylate of (S)-1-amino-3-hydrochlorate 1200g, productive rate: 82.2%.MS?m/z145(M+H)

Technique scheme has only embodied the optimal technical scheme of technical solution of the present invention, and those skilled in the art have all embodied principle of the present invention to some changes that wherein some part may be made, within belonging to protection scope of the present invention.
Claims (1)
1. the preparation method of the chloro-2-propylate of (S)-1-amino-3-hydrochlorate, it is characterized in that, described reaction be take the S-epoxy chloropropane as raw material, benzylamine and hydrochloric acid are auxiliary reagent, for the chloro-2-propylate of one kettle way preparation (S)-1-amino-3-hydrochlorate, it is characterized in that described reaction comprises the following steps:
(1) take ethanol as solvent, S-epoxy chloropropane and benzylamine are reacted at normal temperatures, obtain the affixture intermediate;
(2) add the concentrated hydrochloric acid back flow reaction in the reaction solution of step (1), then decompression steams solvent, obtains the chloro-2-propylate of (S)-1-amino-3-hydrochlorate.
