実験手順
To a mixture containing 16.82 g (0.101 mole) of 2,4-dimethoxybenzylamine and anhydrous magnesium sulfate in 150 ml of methylene chloride at 25° is added a solution of 10.05 g (0.114 mole) of methyl glyoxalate in 20 ml of methylene chloride. The reaction mixture is stirred at room temperature overnight (15 hours) and then is filtered and the solvents are removed in vacuo to afford the imine as a dark orange gum.
