Reaktionsschritte
Ammonium chloride (38 g) was added to a solution of 4-bromo-2-(tert-butyl)-6-nitrophenyl methyl ether (20.6 g) in methanol-water (140 ml-140 ml) and iron (20 g) was gradually added while heating to reflux. The mixture was heated to reflux for 2 hours and then the reaction mixture was filtered through celite. The filtrate was concentrated under reduced pressure, ethyl acetate was added to the residue and the mixture was washed 3 times with brine. The organic layer was dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure to yield a crude product of the title compound (16.65 g) as a brown oil.
