2,3-Dihydro-5,6-dimethylpyrazine Use and Manufacturing

To a solution of ethylene diamine (13 g, 216 mmol) in anhydrous ether (600 mL) was added 2, 3-butanedione (18.6 g, 216 mmol, in 200 mL anhydrous ether) dropwise over 2 hours. The resulting mixture was stirred at ambient temperature. After 3 hours, the clear solution was concentrated in vacuo to afford a brown oil. Purification by vacuum distillation afforded 16.6 g (70percent yield) of 5, 6-dimethyl-2, 3- dihydropyrazine, a compound of formula (F), as clear, yellow oil ; b. p. 60°C/16 mm Hg, NMR (CD3) 3.3 (br s, 4), 2.1 (s, 6) ppm.To a solution of ethylene diamine (13 g, 216 mmol) in anhydrous ether (600 mL) was added 2, 3-butanedione (18.6 g, 216 mmol, in 200 mL anhydrous ether) dropwise over 2 hours.
