Solid α-(6-(benzyloxy)-2-naphthyloxymethyl)-3-pyridinepropanol (0.90 g; from Example 29 above) was dissolved in dry ethanol (20 ml) and hydrogenated for 2 hours at 5 atmospheres pressure using palladium on carbon (10%, 1 spatula end) as catalyst. The reaction was filtered through Celite and the residue washed with ethanol. The combined filtrate and washings were concentrated under reduced pressure and the residue obtained purified by column chromatography over silica eluting with dichloromethane:methanol (95:5) to give a white solid (0.55 g).
