Reaction Steps

A mixture of 10 g (0. 037 mole) of 3,5-dimethoxy-4-hydroxy-2,β-dinitrostyrene and 10 g of palladium hydroxide on charcoal in 400 cm3 of ethanol and 7 cm3 of formic acid is heated under reflux for 3 hours. After cooling, the reaction mixture is filtered through Celite. The filtrate is evaporated to dryness. The residue is redissolved in dichloromethane and the solution is filtered on silica gel. After distillation of the solvent under reduced pressure and recrystallization from diisopropyl ether, 1 g of the desired product is obtained in the form of a whitish solid (yield =14%).
