実験手順
To a mixture of ethyl 4-oxo-3H-phthalazin-1-ylacetate (11.6 g.) and sodium hydride (288 g; 50% w/w dispersion in mineral oil) in dimethylformamide (150 ml) was added 5-bromo-2-bromomethylbenzothiazole (16.8 g) and the resulting mixture stirred at room temperature for 1 hour. This reaction mixture was poured over ice-water (500 ml.); sufficient 10% HCl was added to adjust the pH to about 4.0 and the precipitated crude solid was collected. This was chromatographed over silica gel to obtain the product (yield: 5.6 g; m.p. 160°-161° C.).
