Synthetic methodologies for the preparation of substituted 5‐nitro‐ and 5‐aminoanthra[1,9‐ cd ]‐pyrazol‐6(2 H )‐ones, 4 and 5 respectively, substituted with a basic side at N‐2 and dioxy substitution in the A‐ring, are reported. These compounds are essentially devoid of activity against in vitro L1210 leukemia and in vivo murine P388 leukemia.
