Procedure
21 g (179 mmol) of gamma-vinylbutyrolactone prepared as in Example 1 were stirred with 125 g of 40% strength aqueous methylamine in an autoclave at 280° C. for two hours. After cooling, the reaction mixture was concentrated at 50° C./20 mbar. The residue (22.7 g) was distilled using a spinning band column to yield 10.3 g (46%) of 5-vinyl-N-methylpyrrolidone.
