Yield:-

Reaction Conditions:

with hydrogenchloride;n-butyllithium in hexane;

Steps:

(Compound of Formula (I))

(Compound of Formula (I)) Butyllithium (50 mL, 1.65M in hexane) was added under nitrogen to a stirred suspension of 2,6-dibromopyridine (19.5 g) in dry ether (200 mL) at -50°. After 0.75 hr a solution of 4-tolunitrile (10 g) in ether (50 mL) was added; stirring was continued at -50° for 3 hrs. The mixture was allowed to warm to -30° and treated with hydrochloric acid (200 mL, 2M). The precipitated solid was collected, washed with water, and recrystallized from aqueous ethanol. The 2-bromo-6-(4-toluoyl)pyridine formed colourless needles (12.2 g) m.p. 97°-98°. A
