실험 절차

To a solution of 1-(4-bromophenyl)propan-2-amine (0.5 g, 2 mmol) in methylene chloride (5 mL) was added pyridine (380 uL, 4.7 mmol) and methyl chloroformate (270 uL, 3.5 mmol, Aldrich, Cat. No. M35304). The reaction mixture was stirred at r.t. overnight, and concentrated under reduced pressure. The residue was dissolved in EtOAc, and washed with NaHCO3 aqueous solution, 1N HCl aqueous solution and brine. The organic layer was dried with MgSO4, filtered, and concentrated under reduced pressure. The residue was purified by flash chromatograph on a silica gel column using 25% Ethyl acetate in hexane to afford the desired compound. LCMS (M+H)+: m/z=272.2.
