Procedure
A mixture of 10.5 g. (0.05 mol.) of 2-p-hydroxyphenylbenzofuran and 47 g. (0.25 mol.) of 1,2-dibromoethane in 200 ml. of 3-pentanone containing 46 g. (0.3 mol.) of potassium carbonate was heated at 100° for 12 hours. The mixture was filtered while hot and the solid remaining was washed with hot acetone. The combined filtrate and washings were concentrated to give 2-[4'-(2-bromoethoxy)phenyl]benzofuran.
