Reaction Steps

6 g of 6-acetoxy-2,5,7,8-tetramethyl-2-(5-nitropyridin-2-yloxymethyl)chroman (prepared as described in Preparation 36) were dissolved in a mixture of 80 ml of methanol and 15 ml of benzene, and, in the presence of 1.5 g of 10% w/w palladium-on-carbon, were catalytically reduced at room temperature for about 20 hours under about 1 atmosphere (about 1 bar) pressure of hydrogen. The catalyst was filtered off, and the filtrate was condensed by evaporation under reduced pressure, to give the title compound.
