実験手順
A mixture of 2-chloro-5-(4-(trifluoromethyl)phenyl)oxazole 31 (0.651 g, 2.63 mmol) and N-(3-aminophenyl)-1-phenylmethanesulfonamide 26 (0.69 g, 2.63 mmol) in 2-propanol (50 mL) was heated to 80° C. for 18 h with stirring. Upon cooling, solvent was evaporated and silica column purified (Biotage) (Acetone/hexane as an eluent) to provide 1-phenyl-N-(3-((5-(4-(trifluoromethyl)phenyl)oxazol-2-yl)amino) phenyl) methane sulfonamide. 34 (0.407 g, 33% yield) as a solid. MS (ES) m/z 474 (M+H+).
