Participants

Reaction Steps

To a solution of 4-bromo-2-fluoro-5-methylaniline (500 mg, 2.45 mmol.) in THF (3 mL) was added the 2-fluoro-5-(trifluoromethyl)phenyl isocyanate (625 mg, 3.0 mmol). The reaction generated a white solid within 10 min. An additional portion of THF (3 mL) was added and the mixture dissolved. TLC analysis (1:1 Et2O:Hex) indicated that the reaction was complete. The product was purified by flash column chromatography (Hex:Et2O 2:1 to Et2O). 1H-NMR (DMSO-d6) δ 9.37 (d, J=2.8 Hz, 1H), 9.17 (d, J=2.4 Hz, 1H), 8.61 (dd, J=7.2, 2 Hz, 1H), 8.19 (d, J=8.0 Hz, 1H), 7.55 (d, J=10.8 Hz, 1H), 7.49 (dd, J=10.8, 8.8 Hz, 2H), 7.39 (m, 1H), 2.29 (s, 3H); MS [M+H]+=409.3, LCMS RT=3.91 min.
