The Grignard reaction of 1-(tert-butoxycarbonyl)piperidin-3-one (I) with 2-methylphenylmagnesium 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-6-methyl-4-[3-(2-methylphenyl)-1,2,3,6-tetrahydropyridin-1-yl]pyrimidine (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.
