Reaction Steps

A mixture of benzoylacetonitrile (9.94 g, 0.0685 mole), malononitrile (11.3 g, 0.17 mole), ammonium acetate (5.4 g, 0.07 mole) and ethanol (100 mL) was heated at reflux for 1.5 hours. After cooling to room temperature, the reaction mixture was diluted with water (50 mL) and concentrated hydrochloric acid (7.5 mL) was added dropwise over 5 minutes. The resulting precipitate was collected by filtration and washed with water and ligroin. The yield was 10.0 g (76%), m.p. 92°-98° C.
