実験手順

To a suspension of 5-amino-2-methyl-N-(pyrimidin-5-yl)benzamide 26 (0.068 g, 0.30 mmol) in benzene (5 mL) was added 1-isocyanato-3-(trifluoromethyl)benzene (0.046 mL, 0.33 mmol). The reaction was heated at 75° C. for 2 hours, producing a solid precipitate. The mixture was concentrated and chromatographed on silica gel with 94/6 CH2Cl2/MeOH to afford 1-(4-methyl-3-(pyrimidin-5-ylcarbamoyl)phenyl)-3-(3-(trifluoromethyl)phenyl)urea 27 as a white solid. MS m/z: found 416 [MH+], calc. for C20H16F3N5O2=415.13.
