実験手順

Under a nitrogen atmosphere an ethanolic solution of anhydrous HCl (5N; 0.40 mL) is dropped into a stirred suspension of 2-[2-(N-tert-butoxycarbonylamino)ethyl]-5-[[2-(N-tert-butoxycarbonylamino)ethyl]amino]isoquino[8,7,6-cd]indazole-6(2H)-one of Example 10 (0.104 g) in absolute ethanol (2.1 mL). Initial dissolution of the starting material followed by precipitation of a dark-red solid is observed during the addition of ethanolic HCl. This solid is redissolved with absolute ethanol and the solution is heated to 40° C. for 2 h, 30'. The gradual formation of a red-amaranth precipitate is observed during the heating. After cooling to room temperature diethyl ether (10 mL) is added and the precipitate is collected by suction filtration under a nitrogen blanket, to give 2-[2-(amino)ethyl]-5-[[2-(amino)ethyl]amino]isoquino[8,7,6-cd]indazole-6(2H)-one trihydrochloride (0.070 g).
