Procedure

2-Nitro-1,4-bis-(2-acetoxyethoxy)hydroquinone (115 g) was dissolved in ethanol at 50° C. and reduced with hydrogen in the presence of palladium catalyst (2 g, 5% Pd/C). When uptake of hydrogen ceased the solution was screened to remove the catalyst and the filtrates allowed to cool to room temperature. The crystalline solid was isolated by filtration and dried under vacuum to give 90 g of product.
