Reaction Steps

A mixture of 3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetic acid (1.45 g, 4.6 mmol), 2-(2-(4-ethoxycarbonylphenyl)ethynyl)pyrrolidine (1.12 g, 4.6 mmol), EDC 1.32 g (6.9 mmol), DMAP (562 mg, 4.6 mmol) in DMF (20 ml-) was stirred overnight. The mixture was poured into 1 N HCl and the solid was collected with suction. The solid was dissolved in CHCl3 and dried over MgSO4. After removal of the solvent, the residue was chromatographed on silica-gel with CHCl3-MeOH (100:1, v/v) as eluent to give 2.20 g (89%) ethyl 4-[2-[1-[3-methoxy-4-(N′-(2-methylphenyl)ureido]phenylacetyl]-2-pyrrolidinyl]ethynyl]benzoate as a white amorphous solid.
