Reaktionsschritte

A 500 ml 3-necked round bottom flask equipped with a reflux condenser, a mechanical stirrer, a thermometer, a dropping funnel and an efficient N2 blanket, is charged with 2-aminoethyl methacrylate hydrochloride 41.4 g (0.25 mole), 50mg of hydroquinone and 300 ml of chloroform. The contents are cooled to between 0 and 5 degrees C. and stirred. Through a dropping funnel 25.3 g (0.25 mole) of triethylamine and 13.3 g (0.25 mole) of vinyl isocyanate in 50 ml of chloroform are added into the reaction flask and maintained at between 0 and 5 degrees C. The temperature is allowed to rise to room temperature with the contents stirred constantly overnight, passed through a silica gel column and dried with magnesium sulfate. The contents are then evaporated under reduced pressure to give the named product.
