실험 절차

Bromoacetyl bromide (588 μL, 6.75 mmol) was added slowly to a stirred solution of tert-butyl 2-(benzyloxy)-1-{[(4-fluorobenzyl)amino]-methyl}ethylcarbamate (2.39 g, 6.14 mmol) and triethylamine (941 μL, 6.75 mmol) in anhydrous THF (12 mL) at 0° C. under inert atmosphere. After stirring for 20 min, the reaction was poured into ice water and extracted twice with diethyl ether. The combined organic layers were washed twice with brine, dried over Na2SO4, and concentrated in vacuo. The resulting orange/brown oil was purified by silica gel chromatography (10% to 40% EtOAc/hexanes) to afford the title compound as a red-orange oil. 1H NMR (500 MHz, CDCl3) δ 7.40-7.21 (m, 6H), 7.16-6.96 (m, 3H), 5.20 (d, J=8.0 Hz, 1H), 5.01 (d, J=9.0 Hz, 1H), 4.75-4.66 (m, 1H), 4.59-4.48 (m, 2H), 4.39 (d, J=15.0 Hz, 1H), 4.04-3.92 (m, 2H), 3.87-3.28 (m, 4H), 1.43 (s, 9H). ES MS (M+1−100, for loss of BOC group)=409.4.
