合成路线1
该中间体在本合成路线中的序号:(III)The condensation of 6-fluoro-2-methylindole (I) with beta-chloropropionitrile (II) by means of ethylmagnesium iodide (that forms the magnesium salt of (I)) in refluxing ether gives 3-(6-fluoro-2-methyl-3-indolyl)propionitrite (III), which is hydrolyzed with KOH in refluxing water yielding 3-(6-fluoro-2-methyl-3-indolyl)propionic acid (IV) (1). The condensation of (IV) with 4-hydroxy-4-(3-trifluoromethylphenyl)piperidine (V) by means of ethyl chloroformate and triethylamine in refluxing THF affords 1-[3-(6-fluoro-2-methyl-3-indolyl)propionyl]-4-hydroxy-4-(3-trifluromethylphenyl)piperidine (VI), which is reduced with LiAlH4 in refluxing THF giving 1-[3-(6-fluoro-2-methyl-3-indolyl)propyl]-4-hydroxy-4-(3-trifluoromethylphenyl)piperidine (VII). The ozonolysis of (VII) in HOAc affords 1-[3-(2-acetamido-4-fluorobenzoyl)propyl]-4-hydroxy-4-(3-trifluoromethylphenyl)piperidine (VIII), which is finally hydrolyzed with concentrated HCl in refluxing EtOH
