実験手順
To a solution of 5-bromopyridin-2-yl amine (1.190 g, 6.88 mmol, 1.0 eq.) in THF (20 mL), add 3-trifluoromethylphenyl isocyanate (0.96 mL, 6.88 mmol, 1.0 eq.) in a drop-wise manner at room temperature. Stir the reaction mixture at room temperature for 30 minutes. Filter the solid and wash with MeOH (2×10 mL). Dry the solid to afford 1.81 g (5.0 mmol, 73%) of the title compound. MS (ES), m/z 360, 362 (M+1).
