合成路线1
该中间体在本合成路线中的序号：(VIII)The Grignard reaction of 1-(tert-butoxycarbonyl)piperidin-4-one (I) with 3-fluorophenylmagnesium bromide (II) in THF gives the tertiary alcohol (III), which is dehydrated with TFA or HCl in dioxane yielding the tetrahydropyridine (IV). The condensation of (IV) with 2,4-dichloro-6-methylpyrimidine (V) by means of DIEA in ethanol affords 2-chloro-4-[4-(3-fluorophenyl)-1,2,3,6-tetrahydropyridin-1-yl]-6-methylpyrimidine (VI), which is further condensed with 4-isopropyl-2-(methylsulfanyl)aniline (VII) by means of DIEA in refluxing ethylene glycol to give the secondary amine (VIII). Finally, this compound is alkylated with ethyl iodide and NaH in DMF.
