実験手順
In acetic acid (100 ml) was dissolved N-(1,3-dimethoxypropan-2-yl)-N-methyl-4-nitrobenzylamine (3.1 g), and to the mixture was added reduced iron (3.2 g) little by little. The mixture was stirred at room temperature overnight, and the solvent was evaporated. To the residue was added ethyl acetate, and precipitates were filtered off. The filtrate was washed with sodium hydroxide solution, water and saturated brine, and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the residue dissolved in ethyl acetate. To the mixture was added 4N hydrochloric acid-ethyl acetate, and precipitates were filtered and washed with diethylether. The mixture was dissolved in water, and the mixture was neutralized with 1N sodium hydroxide solution and extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated to give 4-((N-(1,3-dimethoxypropan-2-yl)-N-methylamino)methyl)aniline (2.4 g) as red oil.
