Quinoxaline-2-carbaldehyde → 2-Ethenylquinoxaline
Reaction equation
[N:1]1[C:10]2[C:5](=[CH:6][CH:7]=[CH:8][CH:9]=2)[N:4]=[CH:3][C:2]=1[CH:11]=O.[CH:13](C1C=NC=NC=1)=C>>[CH:11]([C:2]1[CH:3]=[N:4][C:5]2[C:10](=[CH:9][CH:8]=[CH:7][CH:6]=2)[N:1]=1)=[CH2:13]Participants

Procedure
Prepared in a similar manner to that described for Intermediate 2, replacing 2-vinylpyrazine with 2-vinylquinoxaline.* The product was purified by SPE using cyclohexane:ethylacetate (2:1 v/v) as eluent to provide the title compound as an oil. *{2-Vinylquinoxaline was synthesized from quinoxaline-2-carboxaldehyde using the procedure described in Intermediate 10 for 5-vinylpyrimidine}.
