Procedure

--[(2-oxazolin-2-yl)methyl]-2-pyrrolidone, for example, can be obtained by condensation of pyrrolidone and chloroacetic acid to form 2-pyrrolidone acetic acid, where m =I in the above formula (II), or, alternatively, by condensing butyrolactone with glycine, and the starting carboxylic acid condensed with ethanolamine and cyclodehydrated to form 1-[(2-oxazolin-2-yl)methyl]-2-pyrrolidone.
