To a solution of 4-iodoaniline (438 mg, 2.0 mmol) in 15.0 mL 1,2-dichloroethane at rt was added 2-fluoro-5-(trifluoromethyl)phenyl isocyanate (0.304 mL, 2.1 mmol). After 50 minutes 3 mL hexane was added, the mixture cooled to 0° C., the precipitant filtered and rinsed with 10% EtOAc/hexane to give the title compound as a light purple solid (692 mg, 82%). 1H NMR (DSMO-d6) δ: 9.26 (s, 1H), 8.90 (d, J=2.9 Hz, 1H), 8.59 (dd, J=7.3, 2.3 Hz, 1H), 7.60-7.65 (m, 2H), 7.46-7.54 (m, 1H), 7.36-7.43 (m, 1H), 7.29-7.34 (m, 2H).
