4-Methylmorpholine → 4-chloro-3-((trifluoromethyl)phenyl)-N'-(4-(3-methylcarbamoylphenyl)carbamoylphenyl)urea

To a solution of N-(4-chloro-3-((trifluoromethyl)phenyl)-N′-(4-(3-methylcarbamoylphenyl) carboxyaminophenyl)urea (0.14 g, 0.48 mmol), 3-methylcarbamoylaniline (0.080 g, 0.53 mmol), HOBT.H2O (0.14 g, 1.07 mmol), and N-methylmorpholine (0.5 mL, 1.07 mmol) in DMF (3 mL) at 0° C. was added EDCI.HCl (0.10 g, 0.53 mmol). The resulting mixture was allowed to warm to room temp. and was stirred overnight. The resulting mixture was treated with water (10 mL), and extracted with EtOAc (25 mL). The organic phase was concentrated under reduced pressure. The resulting yellow solids were dissolved in EtOAc (3 mL) then filtered through a pad of silica gel (17 g, gradient from 70% EtOAc/30% hexane to 10% MeOH/90% EtOAc) to give N-(4-chloro-3-((trifluoro methyl)phenyl)-N′-(4-(3-methylcarbamoylphenyl)carbamoylphenyl)urea as a white solid (0.097 g, 41%): mp 225-229; TLC (100% EtOAc) Rf 0.23.
