Versuchsvorschrift

A solution of 100 g. of N,N-dimethylethylenediamine in 40 cc. of benzene was added dropwise to a stirring solution of 16.4 g. of 2-vinyl-4,4-dimethyl-5-oxazolone in 50 cc. of benzene. The oxazolone solution contained a few milligrams of t-butylhydroquinone as a polymerization inhibitor. An external water bath was used to maintain the resultant solution at about 25° C. The solution was stirred about 2 hours, filtered through Celite, and evaporated. The residue after evaporation was triturated with hexane and the mixture filtered to provide N-(N',N'-dimethyl-β-aminoethyl)-2-methyl-2-acrylamidopropanoic acid amide as a white solid.
