실험 절차
A mixture of 4-[N′-(2-bromophenyl)ureido]-3-methoxyphenylacetic acid (480 mg, 1.27 mmol), benzyl (S)-4-(2-amino-1-propoxy)benzoate (361 mg, 1.27 mmol), EDC.HCl (364 mg, 1.90 mmol), HOBt (256 mg, 1.89 mmol) and DMAP (31 mg, 0.25 mmol) in DMF (8 ml) was stirred at room temperature overnight. The mixture was diluted with EtOAc, washed with 0.5 N HCl, brine, dried over Na2SO4 and evaporated. The residue was purified by column chromatography on silica-gel with CHCl3 to 5% MeOH in CHCl3 as eluent to give benzyl (S)-4-[2-[4-[N′-(2-bromophenyl)ureido]-3-methoxyphenylacetamido]-1-propoxy]benzoate (476 mg, 58%) as a brown solid. 1H-NMR (CDCl3) δ1.25-1.28 (m, 3 H), 3.51 (s, 2 H), 3.74 (s, 3 H), 3.95-3.97 (m, 2 H), 4.36-4.39 (m, 1 H), 5.33 (s, 2 H), 6.75-6.94 (, 5 H), 7.26-7.70 (m, 8 H), 7.99-8.26 (m, 5 H).
