Reaction Steps

6.78 g (178.8 mmol) of lithium aluminum hydride and 200 ml of anhydrous tetrahydrofuran were mixed and an anhydrous tetrahydrofuran solution of 17.0 g (59.6 mmol) of 1-benzyloxy-2-methoxy-4-(2-nitrovinyl)benzene was added dropwise thereto over about 90 minutes under vigorous stirring. The mixture was refluxed for 2 hours by heating, and then cooled and aqueous sodium hydroxide solution was added to the mixture. The precipitates were filtered off with celite-precoated glass filter and the solvent was distilled off from the filtrate under reduced pressure. The residue was extracted with ethyl acetate, washed with saturated brine, dried over potassium carbonate and the solvent was distilled off under reduced pressure to give 13.67 g of crude 2-(3-methoxy-4-benzyloxyphenyl)ethylamine.
