Procedure

A mixture of (±)-trans-1-(phenylmethyl)-3-hydroxy-4-piperidinemethanol (17.8 g, 0.085 mol) (already described in J. Med. Chem., 16, pp. 156-159 (1973)) in methanol (250 ml) was hydrogenated, at 50° C., with palladium on activated carbon (10%, 2 g) as catalyst. After uptake of H2 (1 equivalent), the catalyst was filtered off and the filtrate was evaporated, yielding 12 g of (±)-trans-3-hydroxy-4-piperidinemethanol (interm. 1-a) (used in next reaction step without further purification). The corresponding cis-isomer is known from J. Org. Chem., 34, pp. 3674-3676 (1969).
