実験手順
A mixture of N-methyl-4-ethoxycarbonylmethylaniline (10 g), sodium hydrogencarbonate (5 g) and water (5 ml) was heated to 90° C. on an oil bath. Ethyl 2-bromomethylbenzoate (12.2 g) was gradually added dropwise to the mixture with stirring. Then, the mixture was stirred for 2 hours at 90° C. The reaction mixture was cooled, and extracted with benzene. The extract was washed with water. The benzene layer was extracted with 2 N-HCl. The aqueous layer was neutralized with potassium carbonate while cooling the layer with ice, and extracted with benzene. The benzene layer was dried over anhydrous magnesium sulfate. When the solvent was distilled off under reduced pressure, 20 g of N-methyl-N(2-ethoxycarbonylbenzyl)-4-ethoxycarbonylmethylaniline was obtained as a light-yellow oily material.
