Reaction Steps

6-(4-{Difluoro-[4-(6-hydroxyhex-1-ynyl)phenoxy]methyl}-3,5-difluorophenyl)hex-5-yn-1-ol is hydrogenated to completion on palladium/active carbon catalystin THF. The catalyst is filtered off, the solvent is removed in vacuo, and the crude product is chromatographed on silica gel with toluene/ethyl acetate (1:2), giving 6-(4-{difluoro-[4-(6-hydroxyhexyl)phenoxy]methyl}-3,5-difluorophenyl)hexan-1-ol as a colourless solid.
