4-Aminopyridine → 4-(2,2,2-Trimethylacetamido)pyridine

Participants

Reaction Steps

To a mixture of 20 g of 4-Aminopyridine and 37 mL of triethylamine in 380 mL of methylene chloride is added 28.8 mL of pivaloyl chloride in a dropwise fashion. After 1 hour at room temperature the reaction mixture is washed with water and sodium bicarbonate solution, dried over magnesium sulfate and the solvent is removed in vacuo. The residue is triturated with hexane to afford 4-trimethylacetamidopyridine as a white solid.
