실험 절차

A mixture of 3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetic acid (261 mg, 0.83 mmol), methyl (S)-3-chloro-4-(2-methylamino-1-propoxy)benzoate (214 mg, 0.83 mmol), EDC(hydrochloride) (239 mg, 1.25 mmol), HOBt (168 mg, 1.24 mmol), and DMAP (20 mg, 0.16 mmol) in DMF (8 mL) was stirred at room temp 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 470 mg (100%) methyl (S)-3-chloro-4-[2-[N-methyl-N-[3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetyl]amino]-1propoxy]benzoate as a pale yellow amorphous solid.
