Abstract: The title compound, C14H18O4, was obtained unintentionally as the major product of an attempted synthesis of (E,E)-2,5-bis[2-(2,4,6-trimethoxyphenyl)ethenyl]pyrazine. The crystal packing features layers based on two weak C-HO hydrogen bonds involving the O atom of the carbonyl group and two OmethoxyCmethoxy interactions [3.109 (2) Å]. The sheets are interconnected via methoxy-methoxy dimers and C-H interactions.
