The 2-ethyl-3,5-dimethylpyrazine is obtained by alkylation of dimethyl-2, 6-pyrazine; the 2,5-dimethyl-3-ethylpyrazine is obtained by alkylation of 2,5-dimethylpyrazine with ethyllithium. A mixture of the two can be obtained by condensation of 2,3-pentanedione with propylenediamine. A mixture of the two is obtained from the side chain alkylation of trimethylpyrazine.2-Ethyl-3,5-dimethylpyrazine 준비 용품 및 원자재
