Reaction Conditions

Reaction Steps

Combine 4-iodo-2-methyl-pyridine (1.1 g, 5 mmol), NBS (0.98 g, 1.1 equiv.) and carbon tetrachloride (50 mL) in a round bottomed flask under nitrogen. Add AIBN (82 mg, 0.1 equiv.) and heat reaction overnight at reflux. Filter the reaction, washing with hexanes. Concentrate filtrate to approximately 10-20 mL volume. Redissolve in THF (20 mL) and cool to 0° C. under nitrogen. Add diethylamine (1.04 mL, 2 equiv.) dropwise via syringe and stir one hour at 0° C. Remove cooling bath and let warm to room temperature. After 6 hours total, concentrate to dryness and purify by silica gel (1:1 Hexanes:Ethyl Acetate→Ethyl Acetate) to give a tan liquid (0.51 g, 35% over 2 steps). MS (ES), m/z 291.0 (M+1).
