実験手順
The epoxide starting material is obtained by reacting 3-fluoro-4-methoxyphenol with 1-bromo-2-propoxyethane. After work up of the reaction mixture 2-fluoro-1-methoxy-4-(2-propoxyethoxy)benzene is obtained which is then reacted with sodium thioethoxide giving 2-fluoro-4-(2-propoxyethoxy)phenol which is then reacted with epichlorhydrin in the presence of a catalytic amount of piperidine.
