Procedure

To a solution of N-(4-chloro-3-((trifluoromethyl)phenyl)-N′-(4-aminophenyl)urea (Method C1d; 0.050 g, 1.52 mmol), mono-methyl isophthalate-(0.25 g, 1.38 mmol), HOBT.H2O (0.41 g, 3.03 mmol) and N-methylmorpholine (0.33 mL, 3.03 mmol) in DMF (8 mL) was added EDCl.HCl (0.29 g, 1.52 mmol). The resulting mixture was stirred at room temp. overnight, diluted with EtOAc (25 mL) and sequentially washed with water (25 mL) and a saturated NaHCO3 solution (25 mL). The organic layer was dried (Na2SO4) and concentrated under reduced pressure. The resulting solids were triturated with an EtOAc solution (80% EtOAc/20% hexane) to give N-(4-chloro-3-((trifluoromethyl)phenyl)-N′-(4-(3-methoxycarbonylphenyl)carboxyaminophenyl)urea (0.27 g, 43%): mp 121-122; TLC (80% EtOAc/20% hexane) Rf 0.75.
