실험 절차
Diketene (1.22 mL, 15.7 mmol, 1.50 equiv) was added at room temperature to a stirred mixture of 3-bromopropylamine hydrobromide (2.30 g, 10.5 mmol, 1.00 equiv) and triethylamine (1.46 mL, 10.5 mmol, 1.00 equiv) in anhydrous THF (20 mL) under argon, and stirring was continued at room temperature for 1 hour. The solvent was removed and the residue was purified by flash chromatography (SiO2, MeOH—CH2Cl2 0:1 to 1:18) to afford a light yellow oil, 2.10 g (90%), which was characterized spectroscopically.
