実験手順

0.51 g (0.31 ml, 2.56 mmol) of trichloromethyl chloroformate (“diphosgene”) are dissolved in 15 ml of dichloromethane, and 1.00 g (5.12 mmol) of 4-methoxybenzyl(2-methoxyethyl)amine and 0.78 g (7.68 mmol) of triethylamine are slowly added. After stirring at room temperature overnight, the mixture is poured into ice-water and extracted three times with dichloromethane, and the organic phase is dried over magnesium sulfate and concentrated to dryness in a rotary evaporator. The crude product is employed without workup directly in the next stage.
