Ethyl (3-Hydroxyphenyl)acetate → Ethyl 3[(2-nitro-3-phenylbenzofuran-5-yl)methoxy]phenylacetate

Participants

Reaction Steps

To a solution of 0.0066 ml. of sodium ethoxide in 50 ml. of ethanol is added 1.2 g. (0.0066 mole) of ethyl 3-hydroxyphenylacetate. The mixture is heated at its reflux temperature for three hours, then 2 g. (0.006 mole) of 5-bromomethyl-2-nitro-3-phenylbenzofuran is added. The mixture is heated at its reflux temperature for 16 hours. On cooling of the reaction mixture a yellow precipitate is obtained which is separated by filtration. Recrystallization from a mixture of hexane and benzene provides ethyl 3[(2-nitro-3-phenylbenzofuran-5-yl)methoxy]phenylacetate, m.p. 67°-68° C.
