The mixture was stirred for a further 2 hours at -52° C. and the precipitated pale precipitate was then filtered off with suction at 0° C. The filtrate was subjected to aqueous work-up and the product was dried and, after concentrating on a rotary evaporator, distilled first at 100° C., and then the residue at 130° C. (in each case 0.1 mm Hg). 174.1 g (53% of theory) of 3- acetamidopropyl methacrylate were obtained in the form of a colorless oil.
