Abstract
Process for the preparation of ester derivatives and para-amino benzoic acid amides, of bases that correspond to the formula ** (See formula) ** wherein: R1 designates an alcoholic or alcoholic radical which may have substituents, particularly a phenyl radical or a chlorine atom; X indicates -O- or -NH-; A denotes a saturated and bivalent aliphatic radical, comprising at least two carbon atoms and whose chain is straight or branched; R2 and R3 denote lower alkyl groups or form a heterocycle with N; and Z denotes H or a substituent such as a lower alkyl group, in particular the para- (carbo-butoxy, carbo-isobutoxy and carbo-benzyloxyamino) benzoates of β -diethylamino ethyl, of the para- ( carbo-butoxy, carbo-isobutoxy and carbo-benzyloxy-amino) benzoates of γ -dibutyl-amino propyl and of the beta- -diethylamino ethylamides of para- (carbo-butoxy and carbo-benzyloxy-amino) benzoic acids, characterizing by the fact that an alkyl alcohol chlorocarbonate is reacted in aqueous solution (see formula) with a salt soluble in water, preferably the hydrochloride or the sulphate of the base (see formula) then the desired hydrochloride is isolated from the reaction product.
