Abstract

Procedure for the preparation of chemical bases, of formula I **(See formula)** (in which X means hydrogen, halogen, C1-6 alkyl or C1-6 alkoxy R means hydrogen or a C1-6 alkyl group Q stands for a hydroxy group, -NH-CO-NH2, -NH-CS-NH2, -NHCOO-alkyl, -NHCOO-aryl, -NHCOO-arylalkyl or 3-oxazolidine-2-yl) characterized by comprising reacting a nitrone derivative of formula II **(See formula)** (in which X and R have the same meaning as indicated above and Ar means an aromatic ring substituted in the ortho and/or para position, by at least one electron donor group) with a compound of formula III NH2 - Q (III) (in which Q is as above) or its acid addition salt in the presence of an acidic substance.
