Reaction Steps
2,6-Difluoro-4-nitrophenol (1.75 g, 10 mmol) and 10% palladium on carbon catalyst (0.3 g) in ethanol (100 ml) were shaken in a closed vessel under an initial hydrogen pressure of 3.5 bar. When hydrogen uptake was complete, the catalyst was filtered off, and the filtrate evaporated to a solid, triturated with petroleum ether, filtered, washed and dried to give the title compound (1.31 g), m.p. indeterminate.
