Procedure

A mixture of toluene-4-sulfonic acid 7-oxo-7H-5,9-diaza-benzo[c]fluoren-6-yl ester (102 mg) (the compound of Reference Example 6c-2) and N,N′-bis-(2-amino-ethyl)-N,N′-dimethyl-propane-1,3-diamine (0.8 ml) was stirred at 50° C. for 20 minutes. The reaction mixture was diluted with dichloromethane. The solution was washed with saturated NaHCO3 solution and dried over magnesium sulfate. The organic layer was evaporated to dryness. The residue was purified by silica gel column chromatography developed by dichloromethane-methanol-ammonia water (25%)=90:10:1. The desired product (37 mg) was obtained as a reddish oil.
