Procedure

Under a nitrogen atmosphere a solution of N-[2-(dimethylamino)ethyl]hydrazine (J. Med. Chem. 7, 493, 1964) (1.86 g) in anhydrous THF (6.0 mL) is added during 30' to the stirred 9:1 mixture of 9-fluoro-6-(p-toluenesulfonyloxy) benzo[g]isoquinoline-5,10-dione and 9-chloro-6-(p-toluenesulfonyloxy) benzo [g]isoquinoline-5,10-dione of Preparative Example 15b (2.4 g) in THF (24 mL) containing N,N-diisopropylethylamine (1.10 mL). A slightly exothermic reaction ensures, and the reaction temperature increases from 20° C. to 25° C. After one hour at room temperature the reaction mixture is poured in water (240 mL) and the suspension obtained is stirred for 30'. The solid is separated by suction, washed with water and dried at 40° C. to give 2-[2-(dimethylamino)ethyl)]-5-(p-toluenesulfonyloxy)isoquino[8,7,6-cd]indazole-6(2H)-one (1.44 g).
