Participants

Reaction Steps

To a solution of sodium (161 mg., 7 mg-atoms) in ethanol (10 ml.) was added 2-isobutoxybenzamidine fluorosulfonate (1.02 g., 3.5 mmole). The mixture was warmed to give a clear solution to which was added a solution of diethyl ethoxymethylenemalonate (756 mg., 3.5 mmole) in ethanol (2 ml.). The solution was heated under reflux for 3 hours. The cooled mixture was added to ice-water (50 ml.) and was acidified to pH 5 with glacial acetic acid. After brief stirring, the solid was collected by filtration, washed with water, and dried to give the title compound (0.94 g., 86%), m.p. 90°-91°.
