Procedure

4-Methoxy-2-[3′,4′,5′-tris(octadecyloxy)benzyloxy]benzaldehyde (93.5 g, 89.2 mmol) was dissolved in THF-methanol (1870 ml+94 ml), and sodium borohydride (4.05 g, 107 mmol) was added at 0° C. After stirring at room temperature for 1.5 hr, 0.2N hydrochloric acid (100 ml) was added at 0° C. to quench the reaction. The solvent was evaporated to about half, and dissolved in chloroform (2400 ml). The mixture was washed twice with 0.1N hydrochloric acid (1200 ml), once with 5% aqueous sodium hydrogen carbonate solution (1200 ml), and once with 20% brine (1200 ml). The solvent was evaporated, and the residue was precipitated with methanol (900 ml) and washed with acetonitrile to give 4-methoxy-2-[3′,4′,5′-tris(octadecyloxy)benzyloxy]benzyl alcohol (92.4 g, 88.0 mmol, 97% yield vs 3,4,5-tris(octadecyloxy)benzyl alcohol).
