Abstract

PURPOSE: To prepare 1,3-dialkyl-2-imidazolidinone useful as an intermediate raw material in organic synthetic chemistry, a phase-transfer catalyst, etc., easily, in high yield, by reacting 1,2-dichloroethane with an alkylamine, and then reacting the product with CO2.
CONSTITUTION: 1,2-Dichloroethane is made to react with an alkylamine of formula RNH2 (R is 1W3C alkyl) to obtain N,N'-alkylethylenediamine of formula II. After removing the by-products from the reaction mixture, or isolating and purifying the compound of formula II, the reaction product is made to react with solid or gaseous CO2 to afford the objective 1,3-dialkyl-2-imidazolidinone of formulaI.
