Reaction Steps

1,2,4-Trifluoro-5-nitrobenzene (10 g, 56.5 mmol) was dissolved in methanol, cooled in ice and treated with 25% sodium methoxide in methanol. After being stirred at room temperature for 6 hours the mixture was diluted with water and extracted with ethyl acetate to give 1,4-difluoro-2-methoxy-5-nitrobenzene (10.1 g). This was dissolved in ethanol (400 ml) and hydrogenated over 10% palladium on carbon to give the title compound (7.8 g).
