Versuchsvorschrift

3-Pyridinehexanol was prepared by hydrogenation of 20.0 g of the crude 6-(3-pyridinyl)-5-hexyn-1-ol, prepared above in Example 105, dissolved in 200 ml of isopropyl alcohol over 2.0 g of 10% palladium on carbon at 1 atmosphere. The crude product obtained after filtration of the catalyst and evaporation of the solvent was evaporatively distilled to yield 15.8 g (89%) of 3-pyridinehexanol as a yellow oil, bp 120°-150° C./0.2 mm which was 90% pure by gas chromatography analysis.
