Abstract
A process for the production of new derivatives of 3- (αIMINOBENCIL) -4-HIDROXI-2 (1H) -PIRIDONA, of formula I, **(See formula)** where each of R1, R2 and R4, which may be the same or different, means hydrogen, fluorine, chlorine, trifluoromethyl or C1 -C4 -alkyl or alkoxy, and R3 is alkyl of 1 to 4 carbon atoms, characterized in that a compound of formula II is reduced, **(See formula)** where R1, R2, and R4 have the previously indicated meanings, in an inert organic solvent.
