Reaction Steps

To a solution of N-(8-phenyloctyl)-4-(2-bromo-ethoxy)-3,5-bis(m-trifluoromethylphenyl)benzamide (1.48 g, 2.05 mmol, 1 eq) in acetone (21 mL) was added K2CO3 (1.42 g, 10.25 mmol, 5 eq) and methyl 2,4-dihydroxybenzoate (0.340 g, 2.05 mmol, 1.0 eq). The reaction was heated at reflux for overnight, cooled to rt and concentrated in vacuo. The residue was partitioned between EtOAc and brine, dried over MgSO4 and concentrated in vacuo. The residue was purified by flash chromatography (30% EtOAc:hexane) to afford 2-hydroxy-4-{2-[5′-(8-phenyl-octylcarbamoyl)-3,3″-bis-trifluoromethyl-[1,1′:3′,1″]terphenyl-2′-yloxy]-ethoxy}-benzoic acid methyl ester (0.98 g, 60%) as a colorless oil. 1H NMR (CDCl3) δ 10.90 (s, 1H); 7.92–7.78 (m, 7H); 7.66–7.50 (m, 4H); 7.27–7.12 (m, 5H); 6.18–6.10 (m, 3H); 3.92 (s, 3H); 3.66–3.40 (m, 6H); 2.58 (t, 2H); 1.60 (m, 4H); 1.28 (m, 8H).
