実験手順

To a solution of dimethyl amine (0.9 mL of a 5.6 M solution in ethanol) in THF (20 mL), a solution of methyl 4-(bromomethyl)-3-methoxybenzoate (500 mg, 2.06 mmol) was added. The mixture was stirred at rt for 35 min before it was diluted with water (150 mL) and sat. aq. Na2CO3-solution (50 mL) and extracted with EA (70 mL). The org. extract was separated, dried over Na2SO4, filtered, evaporated and dried to give methyl 4-dimethylaminomethyl-3-methoxy-benzoate as a colourless oil (420 mg). LC-MS: tR=0.61 min, [M+1]+=224.04.
