Procedure
A mixture of 2-bromo-6-chloro-4-trifluoromethyl aniline (1.00 g, 3.64 mmol), trimethylboroxine (0.66 ml, 0.59 g, 4.47 mmol), potassium carbonate (1.00 g, 7.30 mmol) and catalytic amount (10%) Pd(PPh3)4 in DMF (5 ml) was heated to 90° C. for 14 h. Water (20 ml) was added. The mixture was extracted with ethyl acetate (3×50 ml). The combined EtOAc layers were washed with brine and dried over sodium sulfate. The titled compound was obtained as a colorless oil after a flash column using EtOAc:hexane (1:9) as the elute. 1H NMR (CDCl3, 500 MHz): δ 7.43 (s, 1H), 7.24 (s, 1H), 4.38 (br s, 2H), 2.22 (s, 3H).
