Procedure

To a mixture in THF (50 mL) of 4.4-bis(4-(2-quinolylmethoxy)phenyl)-pentanoic acid 2-quinolylmethyl ester (2.1 g, 3 mmol), prepared as in Example 1, and sodium borohydride (380 mg, 10 mmol) was added dropwise methanol at 50°-55° C. and the mixture was stirred for 30 minutes. The mixture was cooled to room temperature, poured into water (50 mL) and acidified to pH 4. The resulting mixture was extracted with ethyl acetate, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by chromatography on silica gel (methylene chloride-ethyl acetate 3:1) to afford 1.46 g (88%) of 4,4-bis(4-(2-quinolyl-methoxy)phenyl)pentan-1-ol: 1H NMR (300 MHz, DMSO--d6) d 1.18 (m, 2H), 1.48 (s, 3H), 2.00 (m, 2H), 3.34 (m, 2H), 4.34 (t, 1H, J=6 Hz), 5.30 (s, 4H), 6.96 (d, 4H, J=9 Hz), 7.09 (d, 4H, J=9 Hz), 7.64 (m, 4H), 7.79 (m, 2H), 8.00 (t, 4H, J=8 Hz), 8.41 (d, 2H, J=8 Hz); MS (DCI--NH3) m/e 555 (M+H)+. Anal. Calc'd. for C37H34N2O3. 0.5 H2O: C, 78.84; H, 6.44; N, 4.97. Found: C, 78.67; H, 5.95; N, 4.70.
