合成路线1
该中间体在本合成路线中的序号：(XIII)In an alternative method, 2,4'-dipyridyl (XI) was alkylated with 3-bromopropylamine hydrobromide (VII) in hot DMF to provide the pyridinium salt (XII). Reduction of (XII) with NaBH4 gave the tetrahydropyridine (XIII), which was further hydrogenated in the presence of Pearlman's catalyst to yield the intermediate pyridylpiperidine (X).
