合成路线1
Acylation of 4-piperidone ethylene ketal (I) with 3-chloro-4-fluorobenzoyl chloride (II) in the presence of Et3N gave amide (III). After ketal hydrolysis of (III) using 80% formic acid and CuSO4, treatment of the resulting N-acyl piperidone (IV) with dimethyloxosulfonium methylide provided epoxide (V). Subsequent ring opening of (V) with HF-pyridine complex afforded the fluoro alcohol (VI), which was converted to tosylate (VII). Then, Gabriel synthesis via the corresponding phthalimide (VIII) produced amine (IX). The title compound was then obtained by condensation of 6-(2-furanyl)pyridine-2-carboxaldehyde (X) with amine (IX), followed by reduction of the intermediate imine with KBH4 in MeOH.
