Abstract

N(1) - [Bz - 11 - benzanthronyl] - pyrazolanthrones are made by condensing Bz-1-nitrobenzanthrone with a pyrazolanthrone in the presence of a dialkylformamide and potassium carbonate at a temperature in the range of from about 120 DEG to about 155 DEG C. In examples, Bz-1-nitrobenzanthrone is condensed with (1) pyrazolanthrone, (2) 8-chloropyrazolanthrone and (3) 8-ethoxy-pyrazolanthrone. The compounds are dye intermediates.
