実験手順

To a solution of 4-(3-Methoxy-4-nitro-phenoxy)-1-methyl-piperidine (3.0 g, 11.3 mmol) in ethanol (50 mL), 5% palladium on carbon (300 mg) is added under a nitrogen atmosphere. The reaction vessel is fitted with a balloon adapter and charged with hydrogen and evacuated three times until the reaction is under a hydrogen atmosphere. The reaction is allowed to stir overnight. The reaction mixture is filtered through a pad of Celite and washed with methanol. The filtrate is concentrated in vacuo to afford 2-Methoxy-4-(1-methyl-piperidin-4-yloxy)-phenylamine in quantitative yield (2.7 g).
