Patent number: 5849749Abstract: The 6-(hydroxymethyl-ethyl)pyridines are prepared by a process in which the 3-hydroxymethylpyridines which are hydroxyl-protected in the 6-position are oxidized to the 3-aldehyde, this is then converted into the corresponding oxoheptenoic acid derivative using a Wittig-Homer reaction, after this the oxo group is reduced to the hydroxyl group and then the isomers are separated by chromatography.
