Reaction Steps

In a similar manner to Example 4, 3-methoxy-6-{2-[(3-{[2-(3-methoxy-4-methyl-7-oxo-7H-5,10-diaza-benzo[c]fluoren-6-ylamino)-ethyl]-methyl-amino}-propyl)-methyl-amino]-ethylamino}-4-methyl-5,10-diaza-benzo[c]fluoren-7-one was obtained starting from toluene-4-sulfonic acid 3-methoxy-4-methyl-7-oxo-7H-5,10-diaza-benzo[c]fluoren-6-yl ester (the compound of Reference Example 2c-1) and N,N′-bis-(2-amino-ethyl)-N,N′-dimethyl-propane-1,3-diamine. The desired product was obtained as a reddish powder.
