(1.O.h) 430 mg of benzyl (2S 3S,5R)-2-hexyl-3-hydroxy-5-[(tetrahydro-2H-pyran-2-yl)oxy]hexadecanoate in 10 ml of THF are treated with Pd/C 10% and hydrogenated for 3 hours. The catalyst is filtered off and, after evaporation of the filtrate, the crude product is chromatographed on silica gel. There is obtained (2S,3S,5R)-2-hexyl-3-hydroxy-5-[(tetrahydro-2H -pyran-2-yl)oxy]hexadecanoic acid.
