Reaction Steps

69.5 g (242 mmol) 1-(5-benzyloxy-2-hydroxy-3-nitrophenyl)-ethanone are dissolved in 1.4 L methanol and hydrogenated in the presence of 14 g rhodium on charcoal (10%) as catalyst at 3 bar and ambient temperature. Then the catalyst is filtered off and the filtrate is evaporated down. The residue is reacted further without additional purification. Yield: 60.0 g (96%), Rf value=0.45 (dichloromethane on silica gel).
