Reaction Steps

A mixture of 1.04 g. (0.0066 mole) of ethyl isonipecotate and 2 g. (0.006 mole) of 5-bromomethyl-2-nitro-3-phenylbenzofuran in 100 ml. of acetone is heated at reflux for 40 hours. The mixture is cooled and then evaporated to provide a residue which is diluted with diethyl ether. A yellow precipitate is separated by filtration to provide ethyl N-(2-nitro-3-phenylbenzofuran-5-yl)isonipecotate hydrobromide, m.p. 220°-221° C., having the structure
