Reaction Steps

To a solution of 4-bromobenzylbromide (1.26 g, 6.7 mmol) in tetrahydrofuran (10 mL) at 0° C. was added a sodium hydride (60% w/w dispersion in oil; 0.40 g, 10 mmol). The mixture was stirred for 1 hour at room temperature, then 2,5-dichloro pyridine (1 g, 6.7 mmol) was added in one portion and the reaction mixture was heated under reflux overnight. TLC The reaction mixture was cooled and partitioned between ethyl acetate (40 mL) and cold water (10 mL). The organic layer was dried over magnesium sulfate, filtered and evaporated in vacuo to give the crude title compound (1.54 g, 76%). This was used without further purification.
