実験手順

A mixture of pentafluorophenyl 4-[N′-(2-methylphenyl)ureido]phenylacetate (508 mg, 1.13 mmol), methyl (S)-3-chloro-4-(2-amino-1-propoxy)benzoate (275 mg, 1.13 mmol) and Et3N (0.240 mL, 1.72 mmol) in DMF (10 mL) was stirred at room temp overnight. The mixture was diluted with EtOAc, and the solution was washed with 0.5 N HCl, sat. NaHCO3, brine, dried over Na2SO4, and evaporated. The residue was recrystallized from MeOH—CHCl3-n-hexane to give 240 mg (42%) methyl (S)-3-chloro-4-[2-[4-[N′-(2-methylphenyl)ureido]phenylacetylamino]-1-propoxy]benzoate as a white crystalline powder. 1H-NMR (DMSO-d6) δ1.21 (d, 3H, J=6.4 Hz), 2.25 (s, 3 H), 3.33 (s, 2 H), 3.82 (s, 3 H), 4.04-4.14 (m, 3H), 6.90-6.94 (m, 1H), 7.11-7.16 (m, 4H), 7.29-7.38 (m, 3H), 7.83-7.94 (m, 3H), 8.13-8.17 (m, 2H), 9.34 (s, 1 H); MS(FAB) m/z 510 (M30).
