Reaction Steps

A mixture of 3-(5,7-dimethoxy-2-benzothiazolylmethyl)-4-oxo-3H-phthalazin-1-yl acetic acid (0.5 g) and aqueous hydrobromic acid (10 ml, 48%) was refluxed for 4 hours. The hot solution was cooled to room temperature and than poured onto ice-water (50 ml). The resulting pink colored solid was filtered, washed with water (20 ml) and dried. The dried solid was crystallized from methanol to yield the product (0.31 g; m.p. 184° C.).
