Acetonitrile → HCID 86690965, compound

Participants

Reaction Steps

A solution of 1.5 g (10.9 mmol) of methylpyrazine-2-carboxylate and 446 mg (10.9 mmol) of acetonitrile in 16.5 ml of THF was added dropwise to a suspension, heated under reflux, of 434 mg of sodium hydride (60% strength suspension in mineral oil) in 10 ml of THF. The reaction mixture was heated under reflux for 20 h. After cooling, 50 ml of methyl tert-butyl ether were added and the mixture was stirred for 30 minutes. The precipitate formed was filtered off with suction over a frit and dried under oil pump vacuum. This gave 1.77 g (96% of theory) of the title compound which was used without further characterization for the next step.
