10 g (43 mmol) of 2-[4-(3-pyridyl)but-3-enoxy]tetrahydropyran in 200 ml of methanol/water 1:1 (v/v) is acidified by 2N hydrochloric acid and hydrogenated for 16 hours over 2 g 10% palladium on carbon. After filtration, the solvent is removed, the remaining residue is neutralized by saturated aqueous bicarbonate, and the product is extraced with several portions of ether. Purification of the crude product by column chromatography on silica gel yields 15.7 g (87%) of 4-(3-pyridyl)but-Anol as colourless viscous oil. (C9H13NO; F.W. 151.2).
