Reaction Steps

To a solution of ethyl-4-oxo-3-H-phthalazin-1-ylacetate (10.91 g) and dry potassium t-butoxide (5.90 g) in dimethylformamide (50 ml) was added 3-chloropropionitrile (4.92 g) and the resulting solution was stirred for 30 minutes. The solution was then poured onto ice-water (300 ml); sufficient 10% HCl was added to adjust the pH of the resulting mixture to about 4.0 and the precipitated solid was collected and crystallized from methanol (yield: 7.64 g; m.p. 125°-126° C.).
