Reaction Steps

To a solution of N-dodecyl-3-bromo-5-(m-trifluoromethylphenyl)-4-(2-hydroxyethoxy)-benzamide (0.996 g, 1.74 mmol, 1 eq) in CH2Cl2 (9 mL) was added carbon tetrabromide (0.760 g, 2.29 mmol 1.3 eq) and triphenylphosphine (0.603 g, 2.29 mmol, 1.3 eq). The reaction was stirred at overnight at rt and concentrated in vacuo. The residue was purified by flash chromatography (15% EtOAc:hexane) to afford N-dodecyl-3-bromo-4-(2-bromo-ethoxy)-5-(m-trifluoromethylphenyl)-benzamide (0.951 g, 89%) as a colorless oil. . 1H NMR (CDCl3) δ 7.98 (d, 1H); 7.78-7.40 (m, 5H); 6.20 (bt, 1H); 4.52 (dd, 2H); 3.95 (dd, 2H); 3.42 (dd, 2H); 1.50 (m, 2H); 1.30 (m, 18H); 0.92 (t, 3H).
