To a solution of 600 mg of (3S)-3-azidomethyl-1-(tert-butoxycarbonyl)piperidine in 12.5 ml of 20% hydrous tetrahydrofuran, 622 mg of triphenylphosphine was added at room temperature, followed by 45 minutes' refluxing under heating. The reaction liquid was rendered acidic by addition of 0.5 N hydrochloric acid, and successively washed with chloroform and ethyl acetate. Then 4N aqueous sodium hydroxide solution was added to the aqueous layer to render the latter basic, followed by extraction with chloroform and drying over anhydrous sodium sulfate. Distilling the solvent off under reduced pressure, 497 mg of the title compound was obtained.
