A solution of 4-Bromo-2-Iodophenol [207115-22-8] (0.9 g, 3.0 mmol), 4-Methoxyphenylacetylene (0.43 g, 3.3 mmol), PdCl2P(PH3)2 (70 mg), and CuI (50 mg) in DMF/Diethylamine (10 ml) was heated to 60° C. After 1 hr, the reaction was cooled and poured into water which was extracted with EtOAc. The organic layer was dried over MgSO4 and concentrated to give a solid which was triturated with MeOH, filtered to give a solid (0.4 g, 45%): Mp=192-194° C.; 1H NMR (CDCl3) δ 7.77 (d, 2 H, J=9.1 Hz), 7.66 (s, 1 H), 7.37-7.32 (m, 2 H), 6.98 (d, 2 H, J=9.1 Hz), 6.82 (d, 1 H, J=0.8 Hz), 3.87 (s, 3 H).
