Reaction Steps

To a stirred solution of pentafluorophenyl 3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetate (459 mg, 0.96 mmol) and ethyl (R)-3-methoxy-4-(2-aminopropoxy)benzoate (242 mg, 0.96 mmol) in DMF (5 mL) was added Et3N (200 μl, 1.43 mmol), and the resulting mixture was stirred for 2 hr. 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—MeOH (50:1, v/v) as eluent to give 360 mg (69%) ethyl (R)-3-methoxy-4-[2-[3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetylamino]-1-propoxy]benzoate as a colorless crystalline solid. 1H-NMR (CDCl3) δ1.23-1.28 (m, 3 H), 1.38-1.41 (t, 3 H, J=7.3 Hz), 2.32 (s, 3 H), 3.50-4.13 (m, total 11 H), 4.36 (q, 2 H, J=7.3 Hz), 6.65-8.13 (series of m, total 12 H).
