N-(3-hydroxypropyl)acetamide

Conditions: temp:-72.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 184.0 g (1.76 mol) of methacryloyl chloride were added dropwise in the course of 2 hours to an initial mixture, cooled to -72° C., consisting of 206.2 g (1.76 mol) of N-(3-hydroxypropyl)-acetamide, 750 ml of methylene chloride, 228 g (2.25 mol) of triethylamine and 250 mg of 2,6-di-tert.butyl-4-methylphenol. 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. the precipitated pale precipitate was then filtered off with suction at 0° C the product was dried after concentrating on a rotary evaporator distilled first at 100° C. at 130° C.
