New substituted derivatives of N-ethyl(meth)acrylamide and a method for the preparation thereof

摘要

Novel substituted derivatives of N-ethyl(meth)acrylamide complying with the general formula (I): <IMAGE> (I) wherein R=H or -CH3, R1=C1-C8 alkyl and R2=H or C1-C8 alkyl. They may be obtained by a method in which (meth)acrylamide is reacted with a dialkoxy-2,2 ethanal of the formula (II): <IMAGE> (II) wherein R1 has the meaning indicated above to provide a product of formula (I), in which R2=H, and, if desired, by carrying out an etherification with a C1-C8 alkanol.
