실험 절차

4-Chlorophenyl chloroformate (317 μL, 2.24 mmol) in dichloromethane (2 mL) was added to a mixture of 3-acetyl-α, α-dimethylbenzylamine 24 and diisopropylethylamine (390 μL, 2.24 mmol). The reaction mixture was stirred for 2 h. It was then diluted with dichloromethane, washed with 1 N HCl, and then brine. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated. The residue was purified by column chromatography using hexane/ethyl acetate as eluent to give 25 (594 mg, 81%). 1H NMR (CDCl3, 400 MHz) δ 1.73 (s, 6H), 2.60 (s, 3H), 5.65 (s, 1H), 7.02 (d, J=8.4 Hz, 1H), 7.25 (d, J=6 Hz, 2H), 7.44 (t, J=8 Hz, 1H), 7.65 (d, J=7.6 Hz, 1H), 7.82 (d, J=7.6 Hz, 1H), 8.07 (1H, s); 13C NMR (DMSO-d, 100 MHz) δ 27.45, 29.79, 55.50, 124.23, 124.55, 127.31, 129.28, 129.55, 129.79, 130.39, 137.30, 148.70, 150.32, 152.97, 198.64; ESI-HRMS for C18H19NO3Cl (M+H)+ calcd. 332.1053. found 332.1059.
