実験手順: 3-Amino-N-methylbenzamide (371 mg, 2.47 mmol), ethyl 2-bromo-2-phenylacetate (0.29 ml, 1.64 mmol), and DIPEA (0.43 ml, 2.47 mmol) were dissolved in acetonitrile (5 ml) and stirred under microwave irradiation into a sealed vial at 100° C. for 60 minutes (UPLC-MS: complete conversion). Acetonitrile was evaporated, and the crude residue was purified by flash chromatography (DCM/EtOAc=8/2) to obtain ethyl 2-(3-(methylcarbamoyl)phenylamino)-2-phenylacetate (475 mg, 92% yield). Acetonitrile was evaporated the crude residue was purified by flash chromatography (DCM/EtOAc=8/2)

実験手順: 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-((trifluoromethyl)phenyl)-N′-(4-(3-methylcarbamoylphenyl)carbamoylphenyl)urea as a white solid (0.097 g, 41%): mp 225-229; TLC (100% EtOAc) Rf 0.23. to warm to room temp. 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)
