Reaction Steps

A mixture of 2,5-dibromopyridine, benzyl alcohol (1.3 eq), potassium hydroxide pellets (2.4 eq) and dibenzo-18-crown-6 (0.05 eq) in toluene (4 ml/mmol) was refluxed with azeotropic removal of water for 3 hours. After evaporation of the toluene, the resulting mixture was partitioned between chloroform and water. The crude product from the organic phase was recrystallized from ether-hexane to afford the 2-Benzyloxy-5-bromopyridine compound as a solid.
