Procedure

A solution of 2-[2-(dimethylamino)ethyl]-5-(p-toluenesulfonyloxy) isoquino[8,7,6-cd]indazole-6(2H)-one of Example 2 (0.463 g) and 2-(dimethylamino)ethylamine (0.80 mL) in dry pyridine (4.63 mL) is heated at 80° C. for 1 h, 30' under a nitrogen blanket. The solution is then concentrated to dryness and the dark residue obtained is partitioned between brine (30 mL) and ethyl acetate (4×25 mL). The combined organic solutions are dried over Na2SO4 and concentrated to about 3 mL. After addition of n-hexane (12 mL) and stirring for one hour the precipitate is collected by suction and dried at 40° C. under vacuum to give 2-[2-(dimethylamino)ethyl)]5-[[2-(dimethylamino)ethyl]amino]isoquino[8,7,6-cd]indazole-6(2H)-one (0.23 g).
