Alcohol (I) was converted to fluoride (II) by treatment with either diethylaminosulfur trifluoride or the Ishikawa reagent. Subsequent acid cleavage of the Boc protecting group of (III) provided piperidine (VI). Alternatively, alcohol (III) was converted to mesylate (IV), which was displaced with tetrabutylammonium fluoride to afford fluoride (V). The benzamido group of (V) was then hydrolyzed with HCl in aqueous MeOH.
