Reaction Steps
A heptane washed suspension of 7.6 g (0.189 mole) of 60% NaH/mineral oil in 400 ml of anhydrous toluene was treated portion-wise with 25.0 g (0.172 mole) of benzoylacetonitrile under a nitrogen atmosphere. After stirring for 1 hour, 33.0 g (0.189 mole) of ethyl bromoacetate (97%) was added in one portion. The reaction was heated at reflux for 4 hours, then allowed to cool to room temperature and stirred for 20 hours. Water (500 ml) was added, and the toluene layer was extracted with water (500 ml). The toluene layer was dried over MgSO4, filtered, and the solvent evaporated under reduced pressure (42.9 g). The residual oil was fractionally distilled under vacuum to give 21.4 g (54%) of pure product.
