To a mixture of o-chlorophenyl 3-pyridyl ketone (10.0 g, 0.460 mol) and concentrated sulfuric acid at 0° C. is added dropwise a mixture of 90% nitric acid (2.40 ml) and concentrated sulfuric acid (6.0 ml). The resultant mixture is stirred one hour at 0° C., poured onto ice and neutralized with 30% ammonium hydroxide. Filtration and drying affords the title compound as a solid (11.4 g, 94.2%) which is identified by mass spectral analysis.
