実験手順

Dissolved 3-(benzylamino-methyl)-benzoic acid methyl ester (197 mg, 0.77 mmol) in 5 mL of DMF. To this was added 4-cyanophenyl isocyanate (112 mg, 0.78 mmol). The mixture stirred for 48. LC-MS analysis indicated the desired urea. The mixture was diluted with 100 mL EtOAc, washed with 3×50 mL of H2O and 1×20 mL of brine. The organic phase was dried with MgSO4, filtered and concentrated. The resulting residue was applied to a SiO2 prep plate and eluted with 50% EtOAc/hexanes to give two fractions-one clear band and a tail. LC-MS analysis indicated both band and tail were composed of the product. Both fractions were combined to give 105.7 mg of 3-[1-benzyl-3-(4-cyano-phenyl)-ureidomethyl]-benzoic acid methyl ester.
