Abstract
The present invention relates to a kind of Preparation Method And Their Intermediates of 1 receptor antagonists of NK.The present invention provides one kind (5S, 8S) 8 { [1 (3,5 bis- (trifluoromethyl) phenyl) ethyoxyl] methyl } 8 phenyl 1,7 diaza spiros [4,5] preparation method of 2 ketone of the last of the ten Heavenly stems (compound of formula I), it is prepared by Formula II compound, while provides Formula II compound and preparation method thereof.The method of the present invention is easy to operate, reaction condition is mild, safety coefficient is high, side reaction is few, high income, purity are high, reduces production cost and operational risk, is highly suitable for scale industrial production.
Description
Technical field
The invention belongs to medicinal chemistry arts, and in particular to a kind of nk 1 receptor antagonist (5S, 8S) -8- [{ (1R) -1-
[3,5- bis--(trifluoromethyl) phenyl] ethyoxyl }-methyl] -8- phenyl -1,7- diaza-spiros [4.5] decyl- 2- ketone preparation side
Method further relates to key intermediate in this method and preparation method thereof.
Background technology
CN1606545A disclose a kind of entitled (5S, the 8S) -8- of chemistry [(1R) -1- [3,5- is bis--(trifluoromethyl) benzene
Base] ethyoxyl-methyl] -8- phenyl -1,7- diaza-spiro [4.5] decyl- 2- ketone compound, structural formula such as following formula I institute
Show, be neurokinine-1 (NK-1) receptor antagonist, available for a variety of diseases such as treatment vomiting, melancholia, anxiety and coughs.
At present, mainly there are following three kinds about the preparation method of compound of formula I：
CN1606545A discloses a kind of preparation method of compound of formula I, and route 1 specific as follows, the preparation method is with city
Raw material phenylglycine is sold as raw starting material, 17 process steps is have passed through and compound of formula I is just made, and in this method
Many steps isolated or purified is needed before for next operating procedure, technique final step also needs to prepare color by chirality
Spectrum is detached, and seriously constrains production scale.As it can be seen that this method operating procedure is long, separating step is more, process overall yields compared with
Low, the difficulty that industrial amplification production is carried out using the route is larger, and production cost is higher.
