3.8 g of 4,4′-dinitrobenzil was reduced under hydrogen with 3.8 g 10% Ru on C in EtOH. The mixture was filtered through Supracel and the filtrate concentrated under vacuum to dryness. The residue was dissolved in 50% denatured ethanol in water, treated with Darco and filtered. The filtrate was cooled to 0° C. and the resulting crystals were collected and washed with 50% denatured ethanol in water. The crystals were then dried under a heat lamp to give the title compound as a yellow powder.
