Description
Technical field
The invention belongs to medicinal chemistry art, be specifically related to a kind of nk 1 receptor antagonist (5S, 8S)-8-[{ (1R)-1-[3,5-pair-(trifluoromethyl) phenyl] oxyethyl group }-methyl]-8-phenyl-1, the preparation method of 7-diaza-spiro [4.5]-2-in last of the ten Heavenly stems ketone, also relates to key intermediate in the method and preparation method thereof.
Background technology
CN1606545A discloses a kind of chemistry (5S by name, 8S)-8-[{ (1R)-1-[3,5-pair-(trifluoromethyl) phenyl] oxyethyl group }-methyl]-8-phenyl-1, the compound of 7-diaza-spiro [4.5]-2-in last of the ten Heavenly stems ketone, its structural formula is as shown in the formula shown in I, be neurokinine-1 (NK-1) receptor antagonist, can be used for the various diseases such as treatment vomiting, melancholia, anxiety and cough.
At present, the preparation method about formula I mainly contains following three kinds:
CN1606545A discloses a kind of preparation method of formula I, route 1 specific as follows, this preparation method is using commercially available starting material phenylglycine as raw starting material, have passed through 17 process steps just obtained formula I, and a lot of steps in the method need isolated or purified before for next operation steps, technique final step also needs to be separated by chirality preparative chromatography, seriously constrains industrial scale.Visible, the method operation steps is long, and separating step is many, and process overall yields is lower, and adopt this route to carry out the difficulty of industrial amplification production comparatively greatly, production cost is higher.
CN101679257A discloses the preparation method of another kind of formula I, route 2 specific as follows, this preparation method adopts compound 7 in above-mentioned route 1 as raw starting material, through the obtained formula I of 5 step reaction, compared with route 1, this route operation steps is shorter, and the chiral compound 20 of the method adopting into salt-pepper noise splits, and technique is more succinct.But because this route is in the process preparing compound 20, generation be isomer mixture, need to remove isomer wherein by splitting, process recovery ratio significantly reduced.
CN102203062A discloses the preparation method of another kind of formula I, route 3 specific as follows, and this preparation method adopts compound 3 in above-mentioned route 1 as raw starting material, through the obtained formula I of 7 steps reaction.In route 3, the preparation of compound 3 is by the preparation method of the respective compound in above-mentioned route 1, and this preparation method has related to the non-natural S-2-phenylglycocoll of use, needs to be produced by the method for chemical resolution method or asymmetric chemistry synthesis.Utilize the compound 3 in this compound syntheti c route 3 to need very low temperature (– 78 DEG C) under carry out, need a large amount of energy consumptions, need the equipment of special substance simultaneously, the operation easier of very low temperature reaction is comparatively large, and danger is larger.Need in route 3 to adopt the acid (as Hydrogen bromide, hydrofluoric acid etc.) of severe corrosive to remove Cbz protecting group, produce a large amount of acid waste water and waste liquid, be unfavorable for environment protection.In addition, in route 3, compound 27 obtains formula I, in this reaction through the method for catalytic hydrogenation, the side reaction of two (trifluoromethyl) benzyl of 1-(1-methyl)-3,5-can be removed, make to introduce impurity in product, and make process recovery ratio reduce, cost improves.Meanwhile, namely this route introduces two (trifluoromethyl) benzyl of R-1-(1-methyl)-3,5-in the route initial stage, and process costs can raise.
