Disclosed is a process for preparing an aryloxyalkylene amine compound via an aminoethylation reaction comprising: a) reacting an aromatic hydroxyl compound in the presence of a basic catalyst with a 2-oxazolidinone compound of the formula II to form an intermediate reaction product;
wherein R
3
is selected from the group consisting of hydrogen or lower alkyl having 1 to 6 carbon atoms, R
4
is selected from the group consisting of hydrogen, straight or branched chain alkyl having from one to six carbon atoms, phenyl, alkaryl, or arylalkyl; and b) reacting the intermediate product of step a) with a polyalkylene polyamine.

The present invention is a method for producing an N-substituted carbamic acid ester derived from an organic amine from an organic amine, a carbonic acid derivative and a hydroxy composition containing one or more types of hydroxy compounds, wherein the organic amine, the carbonic acid derivative and the hydroxy composition are reacted using a urethane production reaction vessel provided with a condenser, a gas containing the hydroxy composition, the compound having the carbonyl group derived from the carbonic acid derivative, and an ammonia formed as a by-product in the reaction, is introduced into the condenser provided in the urethane production reaction vessel, and the hydroxy composition and the compound having the carbonyl group derived from the carbonic acid derivative are condensed, and wherein a stoichiometric ratio of a hydroxy compound contained in the condensed hydroxy composition to the condensed compound having the carbonyl group derived from the carbonic acid derivative is 1 or more, and a ratio of number of carbonyl groups (—C(═O)—) contained in the compound having the carbonyl group derived from the carbonic acid derivative and number of ammonia molecules contained in the ammonia recovered as a gas from the condenser is 1 or less.
