tert-butyl N-piperidin-3-ylcarbamate;hydrochloride

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of piperidin-3-yl-carbamic acid tert-butyl ester hydrochloride (1.0 g, 4.2 mmol) and ethyl iodoacetate (0.99 g, 4.6 mmol) in acetonitrile (30 mL) is added K2CO3 (1.5 g, 10.5 mmol) and the mixture stirred overnight at room temperature. Volatiles are evaporated under reduced pressure and the residue taken up with water and extracted twice with ethyl acetate. The organic phase is dried over MgSO4 and evaporated under reduced pressure. The resulting material is purified via chromatography over silica gel eluting with a mixture of EtOAc/MeOH (95:5 v/v). Yield: 0.8 g. Volatiles are evaporated under reduced pressure extracted twice with ethyl acetate The organic phase is dried over MgSO4 evaporated under reduced pressure The resulting material is purified via chromatography over silica gel eluting with a mixture of EtOAc/MeOH (95:5 v/v)
