Abstract
Four pathways of synthesis of 1-(2-pyridyl)heptacosa-12,14-diyne, usin g 10-bromodecanl-ol and acetylene or tetradec-1-yne and 2-methylbut-3- yn-2-ol along with alpha-picoline as initial compounds, were studied a nd compared. it was shown that direct introduction of a completely for med unsaturated hydrocarbon chain into an alpha-picoline molecule by a lkylation of its lithium derivative is the most appropriate method for preparation of long-chain 2-alkadiynylpyridines.
