To a solution of 2-hydroxymethyl-5-methylpyrazine (6.2 g) and triethylamine (6.4 ml) in anhydrous benzene (150 ml) dropwise addition was made of a solution of pivaloyl chloride (6.15 ml) in anhydrous benzene (50 ml). The solution was maintained at boiling for 7 hours, the solvent was then evaporated and the residue treated with acetone. After filtration of the insoluble solid, the filtrate was evaporated to dryness and the residue re-dissolved in chloroform. The chloroform solution was first dehydrated and then evaporated to dryness, obtaining 7 g (71.5%) of 5-methyl-2-pyrazinylmethyl pivalate, b.p.=74° C./0.1 mmHg.
