合成路线1
该中间体在本合成路线中的序号:(VI)The reaction of 4-chloro-1-(4-fluorophenyl)-1-butanone (I) with ethylene glycol and p-toluenesulfonic acid in refluxing benzene gives the corresponding ethyleneketal (II), which is condensed with 4-hydroxypiperidine (III) by means of K2CO3 in hot DMF yielding 1-(4-fluorophenyl)-4-(4-hydroxypiperidin-1-yl)-1-butanone ethyleneketal (IV). The Oppenauer oxidation of (IV) with 9-fluorenone and potassium tert-butoxide in hot benzene affords the piperidinone (V), which is condensed with 4-bromo-N-(trimethylsilyl)aniline (VI) by means of BuLi in hot hexane to give 4-[4-(4-aminophenyl)-4-hydroxypiperidin-1-yl]-1-(4-fluorophenyl)-1-butanone (VII). Finally, this compound is treated with CuBr2 and NO in THF.

该中间体在本合成路线中的序号:(VI)The reaction of 4-chloro-1-(4-fluorophenyl)-1-butanone (I) with ethylene glycol and p-toluenesulfonic acid in refluxing benzene gives the corresponding ethylene-ketal (II), which is condensed with 4-hydroxypiperidine (III) by means of K2CO3 in hot DMF yielding 1-(4-fluorophenyl)-4-(4-hydroxypiperidin-1-yl)-1-butanone ethyle-neketal (IV). The Oppenauer oxidation of (IV) with 9-fluorenone and potassium tert-butoxide in hot benzene affords the piperidinone (V), which is condensed with 4-bromo-N-(trimethylsilyl)aniline (VI) by means of BuLi in hot hexane to give 4-[4-(4-aminophenyl)-4-hydroxypiperidin-1-yl]-1-(4-fluorophenyl)-1-butanone (VII). Finally, this compound is treated with Cu82Br2 and NO in THF.
