1-Octanol → Octyl 2-pyrazinecarboxylate

Participants

Reaction Steps

A four-necked flask was charged with 426 g (3.271 mole) of 1-octanol, 100 g (0.806 mole) of pyrazinecarboxylic acid and 5.0 g (0.05 mole) of concentrated sulfuric acid and the internal temperature was maintained under stirring at 97°-100° C. for 8 hours. The reaction mixture was then cooled and transferred to a separatory funnel, in which it was washed with two portions, or a total of 330 g, of 8% aqueous solution of sodium carbonate. The oil layer which separated was washed with water and subjected to distillation under reduced pressure to give 168 g of octyl pyrazinecarboxylate. Yield: 88% (based on pyrazinecarboxylic acid).
