Synthesis of Pyrazoloacridin-9(10H)-ones

Eight pyrazoloacridin-9(10H)-ones were prepared in a three step procedure from 5- and 6-nitroindazoles.Palladium catalysed hydrogenation of nitroindazoles afforded the corresponding 5- and 6-aminoindazoles.These, in turn, reacted with o-chlorobenzoic acid under the conditions of the Ullman reaction to give anthranilic acids.Cyclisation of these acids by means of sulfuric acid led to the title compounds.If phosphoryl chloride was used, instead of sulfuric acid, a 9-chloroacridine derivative was obtained.All the compounds were characterised by 1H NMR spectroscopy.
