Abstract

3-p-Nitrophenylaminobenzofuran was obtained by the reaction of 2,3-dihydrobenzofuran-3-one with p-nitroaniline and was used in the Vilsmeier reaction for the synthesis of 2-formyl-3-p-nitrophenylaminobenzofuran. Treatment of the latter with malononitrile led to 1-p-nitrophenyl-2-imino-3-cyano-1,2-dihydropyrido[3,2-b]benzofuran.
