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}.
