Participants

Reaction Steps

A benzene solution (100 mL) of 2-methylthiophenylboronic acid (2.07 g, 12.3 mmol); 4-bromo-2-fluoro aniline (1.06 g, 5.6 mmol); aq. Na2CO3 (12.5 mL, 2 M, 25 mmol); and tetra n-butyl ammonium bromide (90 mg, 0.3 mmol) was purged with vacuum and Ar. Bis(triphenylphosphine)palladium (II) chloride (195 mg, 0.3 mmol) was added, and the reaction was refluxed 10 h. After cooling, the reaction was diluted with EtOAc and H2O, the layers were separated, the organic was dried over Na2SO4, filtered, and evaporated. The crude product was chromatographed on silica gel (10% EtOAc/hexanes) to yield the desired product (1.05 g, 81%). 1H NMR (CDCl3) δ: 7.29 (m, 2H); 7.18 (m, 2H); 7.09 (dd, 1H, J=11.7, J′=1.8); 7.01 (dd, 1H, J=8.0, J′=1.4); 6.82 (t, 1H, J=9.2); 3.79 (bs, 2H); 2.38 (s, 3H).
