To a solution of 0.177 g. (7.7 g.-atom) of sodium dissolved in 25 ml. of dry methanol was added a solution of 2.4 g. (7.3 mmol.) of 2-p-hydroxyphenyl-3-p-methylbenzoylbenzofuran in 75 ml. of toluene and 10 ml. of methanol. The mixture was refluxed for 15 minutes, then the methanol was removed by distillation. A solution of 1.15 g. (7.7 mmol.) of 3-diethylaminopropyl chloride in 25 ml. of toluene was then added and the resulting mixture was refluxed for 6 hours. After cooling, the reaction mixture was filtered and the filtrate was concentrated to give the title compound.
