Embodiment 1
[0021] 2-{3-[3-(3-aminopropyl)-aminopropyl]-aminopropyl}-2-[(2-dimethylamino)-ethyl]1H-benzisoquinoline-1 , the preparation of 3(2H)-diketoneacetamide pentahydrochloride (17a):
[0022]
[0023] (1) Take 5mmol (1.04g) of compound 14, 7.5mmol (1.0g) of anhydrous potassium carbonate in 50ml of acetonitrile, slowly add 5ml of acetonitrile solution of chloroacetyl chloride (containing 6mmol of chloroacetyl chloride) dropwise under stirring at room temperature, and dropwise , stirred at room temperature overnight, the reaction was completed, vacuum filtration, the solid was collected, washed with acetonitrile, and dried to obtain compound 15a;
[0024] (2) Add 1mmol of compound 15a and 1.5mmol (0.2g) of anhydrous potassium carbonate to 15ml of dry acetonitrile, add 5ml of N,N-dimethylformamide to the mixed solution, stir at 45°C for 15min, then add 1mmol of 5a, Stir at 45°C, monitor by TLC, evaporate the solvent under reduced pressure after the reaction, extract with chloroform...
