Reaction Conditions

Reaction Steps

To a solution of 10.50 of {(3S)-1-(tert-butoxycarbonyl)-3-piperidyl}methyl methanesulfonate in 100 ml of N,N-dimethylformamide, 4.9 g of sodium azide was added at room temperature, followed by 4 hours' stirring at 80° C. under heating. The reaction liquid was diluted with ethyl acetate, washed successively with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and resulting residue was purified by means of silica gel column chromatography (eluting solvent: from hexane to hexane/ethyl acetate=15/1) to provide 7.24 g of the title compound.
