실험 절차
Reaction of ethyl 4-fluorobenzoate with piperidine (3 equivalents) in acetonitrile was carried out at reflux for 4 days. Dilution of the cooled reaction mixture with several volumes of water provided a precipitate, which was filtered to provide ethyl 4-(piperidin-1-yl)benzoate. Reduction of the ester with lithium aluminum hydride (2 equivalents) in tetrahydrofuran gave the corresponding alcohol (Examples 71, 72).
