Reaction Steps

2-(m-Fluoro-p-hydroxyphenyl)-5-heptylpyridine (2 g, 0.007 mol), ethanol (20 ml), potassium hydroxide (0.48 g, 0.008 mol) and n-hexylbromide (1.4 g, 0.008 mol) were heated under reflux with stirring for 4 hours, followed by cooling the resulting reaction fluid, adding water and toluene, transferring the mixture into a separating funnel, washing the resulting organic layer with 2N-NaOH aqueous solution, then washing it with water, distilling off the solvent under reduced pressure, recrystallizing the residue from ethanol, filtering off it in a refrigerator and drying it to obtain the objective final product 2-(m-fluoro-p-hexyloxyphenyl)-5-heptylpyridine (1.7 g).
