Two benzofuro[2,3-c]quinoline derivatives, 6-methylbenzofuro[2,3-c]quinoline and 6(5H)-benzofuro[2,3-c]quinolinone, were synthesized by the condensation of 2-amino-2′-hydroxybenzophenone with chloroacetone, ethyl bromoacetate, or chloroacetonitrile. The benzofuroquinolinone, thus obtained, was converted to 6-chloro and 6-cyanobenzofuro[2,3-c]quinolines.
