PURPOSE: To produce the titled compound useful as a flocculant, thickener, etc., in high yield in a short time, by reacting (meth)acrylic acid with a dialkylaminoalkylamine in the presence of a halogenated carbonic acid ester and a basic substance.
CONSTITUTION: The objective compound of formula III (R2 is H or methyl) can be produced by reacting (meth)acrylic acid with a dialkylamino-alkylamine of formula II (R3 and R4 are 1W4C alkyl; n is 1W3) in the presence of a halogenated carbonic acid ester of formula I (R1 is 1W20C hydrocarbon group; X is halogen) and a basic substance (e.g. trialkylamine, pyridine, etc.). The reaction is carried out optionally under heating or cooling at -50W+50°C. The objective compound of formula I is obtained in a short time, in high yield without producing hardly separable by-products.
