Compounds according to general formula (1) are new. They are readily prepared by the reaction of an N-aryl imidazolidine with an acetic acid derivative, and are useful in the synthesis of pharmaceutically active ethylenediamine derivatives. In this general formula, Ar is an aryl group selected from optionally substituted phenyl and optionally substituted heteroaryl groups. The groups R1 and R2 may be the same or different, and each is selected from H and alkyl groups. Preferably they are selected from H, methyl and ethyl. More preferably they are both H, both methyl, or one is H and the other is methyl. The group Y is selected from OH, O-alkyl, O-aralkyl, 2-cyano-1-pyrrolidyl (2) and a group according to general formula (3). The group X is selected from OH, O-alkyl, O-aralkyl, O-resin, NH2, NH-alkyl, NH-aralkyl, and NH-resin.
