Reaction Steps

2-Allyloxybenzamidine hydrochloride1 (19.07 g., 0.0896 mole) was added to a cooled (ice-water), stirred solution of sodium ethoxide (12.25 g., 0.18 mole) in ethanol (100 ml.). To this cooled, stirred mixture was added a solution of diethyl ethoxymethylenemalonate (19.4 g., 0.0896 mole) in ethanol (15 ml.). The mixture was heated under reflux for 2.5 hours and then allowed to stand at room temperature for 18 hours. The mixture was poured into ice-water containing acetic acid. The solid was collected and recrystallized from cyclohexane to give the title compound (24.0 g., 89%), m.p. 118°-120°. Recrystallization from cyclohexane gave product with m.p. 118.5°-120.5°.
