Procedure

To an ambient solution of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (2.0 g, 9.13 mmol) in tetrahydrofuran (30 mL) was added 2-fluoro-5-trifluoromethylphenyl isocyanate (1.32 mL, 9.13 mmol). After 1 h, the mixture was concentrated under reduced pressure to afford the title compound as a white solid. MS (ESI) m/z 425 [M+H]+.
