Procedure

To a solution in dioxane (10 mL) and methanol (10 mL) of 4,4-bis (4-(2-quinolylmethoxy)phenyl)pentanoic acid (320 mg, 0.56 mmol), prepared as in step 1, was added aqueous 1N sodium hydroxide (0.55 ml, 0.55 mmol). The mixture was then concentrated in vacuo. The product was crystallized by dissolving in CH2Cl2 and precipitation by dropwise addition of a mixture of ethyl acetate-ethyl ether (1:2): 1H NMR (300 MHz, DMSO--d6) d 1.47 (s, 3H), 1.63 (m, 2H), 2.18 (m, 2H), 5.31 (s, 4H), 6.95 (d, 4H, J=9 Hz), 7.08 (d, 4H, J=9 Hz), 7.64 (m, 4H), 7.78 (m, 2H), 8.00 (m, 4H), 8.40 (d, 2H, J=8 Hz); MS (FAB+) m/e 591 (M+H)+ ; (FAB-) 589 (M-H)-. Anal. Calc'd. for C37H31N2 O4Na.0.25 H2O:C, 74.67; H, 5.34; N, 4.71; Found: C, 74.57; H, 5.32; N, 4.52.
