Reaction Steps
1,3-Dimethylbarbituric acid (15.6 g, 0.1 mole), 2,4-dichlorobenzoyl chloride (20.9 g, 0.1 mole) and zinc cyanide (12.9 g, 0.11 mole) were combined in acetonitrile (175 ml). Triethylamine (10.1 g, 0.12 mole) was slowly added with cooling. The reaction mixture was then heated at reflux for one hour. After cooling, the reaction mixture was poured into 2N hydrochloric acid. The resulting product precipitate was filtered and washed with ether to afford 26.4 grams of the desired product, m.p. 123°-127° C. (80.2% yield). The structure was confirmed by instrumental analysis.
