Reaction Steps
The title compound can be prepared through a palladium mediated coupling reaction, using diethyl maleate or fumarate as a common reagent (e.g. Tetrahedron, 2002, 58, 6545). For example, a mixture of 6-bromoquinoxaline (1 eq.), diethyl maleate (2.3 eq.), palladium acetate (0.05 eq.), tri(o-tolyl)phosphine (0.1 eq.) and potassium carbonate (2 eq.) in DMF may be warmed to 100° C. and stirred for 16 hours. Quenching with water, extraction with diethyl ether and purification of the crude product by flash chromatography should provide the title compound.
