Abstract
Procedure for obtaining pyridazine derivatives of formula I: **(See formula)** wherein R1 signifies an alkyl radical of 1 to 4 carbon atoms, R3, R4, R5 and R6 are the same or different and each signifies a hydrogen atom or an alkyl radical of 1 to 4 carbon atoms, or each of R3 and R6 signify a hydrogen atom and R4 and R5 together signify a radical - (CH2) n-, where n signify 2, 3 or 4, and R2 signify a thienyl, furyl or pyridyl radical, or a radical of formula II, **(See formula)** wherein each of R7 and R11 signifies a hydrogen, fluorine, or chlorine atom, or a straight-chain alkyl radical containing 1 to 4 carbon atoms, and each of R8, R9, and R10, may be the same or different, means a hydrogen, fluorine, or chlorine atom, a trifluoromethyl group, or an alkyl radical of 1 to 4 carbon atoms, provided that at least one of R7 and R11 signifies a hydrogen atom, which at least three of R7, R8, R9, R10 and R11 signify a hydrogen atom, and that R9 does not signify a trifluoromethyl group when R8 or R10 signifies a trifluoromethyl group, characterized in that a compound of formula III is reacted, **(See formula)** wherein R2, R3, R4, R5 and R6 have the meanings indicated above, with a compound of formula IV, **(See formula)** wherein R1 has the meaning indicated above, conveniently in an inert organic solvent, and conveniently at a temperature of 60 to 200ºC.
