Versuchsvorschrift

2,5-Bis{(4-methoxyphenyl)amino}terephthalic acid (1.02 gm; 2.5 mmol) and polyphosphoric acid (10 gm) were heated at 160° C. for 15 minutes under a nitrogen atmosphere. The mixture was allowed to cool and then poured into iced water (200 ml) when a purple solid precipitated out. This was filtered off, washed with water and methanol, then dried under vacuum over phosphorous pentoxide to give 948 mg (100%) of 2,9-dimethoxyquinacridone.
