Procedure

A mixture of 69.3 g of (chloromethyl)methoxydimethyl-silane, 40.6 g of potassium cyanate and 42.6 g of 2-pyrrolidinone in 150 ml of anhydrous DMF was heated at 130° C. with stirring for 5 h. The solvent was then removed under reduced pressure. This gave N-[(methoxydimethylsilyl)methyl]-2-oxo-1-pyrrolidinecarboxamide in quantitative yield with a purity of >90% (analysis by 1H NMR, see Example 2a).
