Procedure

To a solution of 2-hydroxy-4-{2-[5′-(8-phenyl-octylcarbamoyl)-3,3″-bis-trifluoromethyl[1,1′:3′,1″]terphenyl-2′-yloxy]-ethoxy}-benzoic acid methyl ester (0.980 g, 1.21 mmol, 1 eq) in EtOH (20 mL) was added 50% NaOH (10 mL) and the reaction was heated at reflux overnight. It was cooled to rt, diluted with H2O, and acidified with 2M HCl to pH 1. It was extracted with EtOAc, dried over MgSO4 and concentrated in vacuo. The residue was purified by flash chromatography (30% EtOAc:hexane) to afford the title compound (0.92 g, 96%) as a white foam. 1H NMR (DMSO-d6) δ 13.60 (bs, 1H); 11.40 (bs, 1H); 8.59 (bt, 1H); 8.00-7.92 (m, 6H); 7.74-7.65 (m, 4H); 7.56 (d, 1H); 7.25-7.10 (m, 5H); 6.08-6.00 (m, 2H); 3.66 (bd, 2H); 3.52 (bd, 2H); 3.25 (dd, 2H); 2.52 (t, 2H); 1.53 (m, 4H); 1.27 (m, 8H); IR (KBr) 3350, 2950, 2850, 1670, 1620, 1550, 1500, 1460, 1320, 1230, 1220, 1160, 1120, 1095, cm−1; mass spectrum [(−)APCI], m/z 792 (M−H)−; Anal.
