Reaction Steps

This 2-(4-heptylphenyl)-5-(4-methyloxyphenyl)pyridine (15 g, 0.042 mol) was dissolved in acetic acid (120 ml), followed by adding a 48% solution of hydrobromic acid (50 ml), refluxing the mixture for 30 hours, cooling the resulting material, pouring it in water, dissolving deposited crystals in 2N-NaOH aqueous solution on heating, adding acetic acid to obtain an acidic solution, filtering off the residue and recrystallizing from EtOH to obtain 2-(4-heptylphenyl)-5-(4-hydroxyphenyl)pyridine (10 g).
