Reaction Steps

A mixture of 2,6-dibromo-4-trifluoromethyl aniline (1.00 g, 3.14 mmol), trimethylboroxin (1.16 ml, 1.04 g, 8.33 mmol), potassium carbonate (1.15 g, 8.33 mmol) and catalytic amount (10%) Pd(PPh3)4 in DMF (5 ml) was heated to 90° C. for 14 h. Water (10 ml) was added. The mixture was extracted with ethyl acetate (3×20 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 7.28 (s, 1H), 7.22 (s, 1H), 3.88 (br s, 2H), 2.21 (s, 6H).
