Reaction Steps
In N,N-dimethylformamide (50 ml) was dissolved 1-(tert-butoxycarbonyl)piperazine (942 mg). After the addition of triethylamine (1.40 ml), ethyl bromoacetate (1.13 ml) was added, followed by stirring overnight at room temperature. The reaction mixture was concentrated under reduced pressure. Ethyl acetate was added to the residue and the mixture was washed with water. The organic layer was dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure. The residue was purified by chromatography on a silica gel column (hexane:ethyl acetate=3:1), whereby a colorless foam was obtained. The resulting substance was dissolved in a saturated hydrochloric acid—ethanol solution (10 ml) and the resulting solution was concentrated under reduced pressure. The solid thus precipitated was collected by filtration while being washed with ethyl acetate, whereby the title compound (841 mg) was obtained as a colorless solid.
